A simple, uncomplicated cataract surgery should not take more than 10 minutes to perform. The best part about a cataract surgery is that most people see almost immediate results and improved vision. However, full recovery can take awhile. Each person heals at a different speed but ideally, your eyes should heal completely in a month. Here are a few tips to help speed up this process and avoid infections and eye injuries.
Take it easy
Just because the surgery takes a short time is no reason to underestimate its importance. Do not drive on the first day and as far as possible avoid driving for the next few days as well. Do not put any extra pressure on your eyes by bending, lifting weights etc. This will ensure that your stitches do not tear open. Try to avoid excessive sneezing and coughing as this can jerk the lens out of place.
Protect your eyes
Wearing sunglasses is a good idea after a cataract surgery. This will protect your delicate eyes against dust, wind etc. Avoid using community swimming pools and hot tubs immediately after such a surgery to lower the risk of infections. Avoid rubbing your eyes aggressively. For the first week, keep your face out of the shower so as to avoid feeling the need to press or rub your eyes as well as to protect them from bacteria in the water.
Your eyes may feel dry and scratchy after a cataract surgery. This is normal and not something to worry about. Your doctor will prescribe eye drops to be taken after the surgery. Use these regularly. Once this is over you may need additional artificial tears or lubricating eye drops. However, do not take these drops without first consulting your doctor. If your eyes are sensitive to the preservatives in bottled eye drops, look for single use ampoules. Ensure that you always wash your hands well before administering the eye drops.
Keep the eye clean
Though washing your face is avoidable, you must still keep the eye clean. Use cotton and a sterile saline wash for the first few days. You can later replace the saline with cool boiled water.
If you feel any deterioration in your vision, pain or excessive discharge in the operated eye, you must immediately consult your doctor. Seeing sudden flashes of light or floaters in your vision should also not be ignored.
We are surrounded by light from everywhere on all sides. Wherever we go, there is some source of light, be it natural or man made. However, exposure to bright light in excess can cause strain to your eyes and if this is continued your vision quality might decrease.
Here are some ways you can adjust light in order to lessen eye stress and to increase your visibility.
Make adjustments in your workplace
According to studies, it has been shown that half of people who work in front of computer screens every day suffer from eye strain. Not only the computer, but the entire lighting around your workstation may also be causing damage.
1. Reduce the brightness of interior lights. Many offices have bright, fancy interior lighting. Use of light bulbs and fluorescents should be lessened.
2. In case of the presence of a window right behind or in front of your work desk, more strain is imposed upon your eyes because of the reflections on the screen. You should change the place or use dark, thick curtains or coat the glasses with anti-reflective material in order to reduce the glare.
3. The blue light emitted from the computer causes a great amount of eye strain. You should adjust the brightness and keep it as low as possible.
Improve your home lighting
For people who spend a lot of time at home working, adjustments should be made to the lighting in order to reduce eye strain.
1. Avoid reading in a dim light room. This can give you headaches and produce eye strain. Any kind of activity where a lot of focus is required in dim or poorly lighted environments causes damage and strain to the eyes.
2. Use desk lamps, reading lamps, under cabinet lights in the kitchen and other types of lights everywhere you work.
3. If you work in a place for more than an hour, a nearby light would make it less stressful for the eyes.
For people with low vision.
1. For people with less power of vision, proper lighting is a must. A 60-year old man would need to double the amount of light to carry out any activity which a man of 30 years would require.
2. People having disorders such as macular degeneration, glaucoma and similar vision disorders need advanced lighting and should consult a doctor for ideas on improving their home lighting.
The presence of proper lighting improves our concentration, our ability to read, and we can differentiate between colors better. Therefore, always opt for the best lighting to avoid giving stress to your eyes.
Eye twitching, tics in the eyelids and spasms in the eye are pretty common. In case of eye twitching, usually the lower eyelid becomes involved. The upper eyelid may also twitch in certain cases. Twitches are not permanent in nature, and they leave after some time. In some cases, eye twitching may last for long durations of time such as weeks or months.
Eye twitching is not a critical medical condition. It is a temporary prickling and irritation in the eyes, which ceases after some time. Common twitching of the eyes is not related to any neurological disorder.
Here are some reasons which cause eye twitches-
Every individual goes through some amount of stress, and the body reacts differently in different people as a result of stress. An eye twitch may be caused due to stress, especially related to strain in the eyes.
In order to reduce stress you should practice yoga, meditation, perform breathing exercises and take a break. Reducing the stress would also cease the twitching in the eyes.
Eye twitching can appear when you are fatigued or very tired. Lack of proper sleep makes your body tired, and this might trigger eye twitching.
You should improve upon your sleeping hours and sleep more.
Vision problems and any issue related to the eyes can cause stress, which may result in constant twitching in your eyes. Whenever too much stress is imposed upon your eyes, they tend to react and twitching occurs. Any problem would make the eyes put in more effort, which results in strain.
You should have an eye check up if you experience an eye strain accompanied by twitching sensation in your eyes.
People who use computers, laptops, tablets and smartphones for a profuse period of time experience pain and twitching in the eyes. There is a 20-20-20 rule to be followed while using such devices, which reduces eye strain and reduces itching or twitching. You can also avail special eyeglasses for people who spend a lot of time on computers.
Intake of an excess amount of caffeine leads to eye twitching. Cut down your doses of coffee, tea, dark chocolates and soft drinks in case of eye twitching and you may observe an easing in the twitching.
Alcohol also leads to eye twitching so you must abstain from alcohol in case you are having twitching in the eyes.
This disorder develops in people who have crossed the age of 50. People who use computers a lot also develop dry eyes, which leads to eye twitching.
Our eyes twitch because of a lot of reasons. You should know the facts right and avoid situations that lead to eye twitching.

Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:
- Distance from the cornea: Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes.Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.
- Difference in vision: Since the lenses of the spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.
- Ease of use: Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in the rigorous physical activity. Contacts are free from all these hassles- they not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles are very uncomfortable to wear during the rains or in humid weather because they fog up.
- Infections and complications: Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect- they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.
- Aesthetic differences: People often prefer contact lenses as they do not change the physical appearance- they help you to look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Colour blindness is not a type of blindness at all; it is an insufficiency in the way some people see colour. Once afflicted by this vision problem, people face difficulty in distinguishing specific colours like red, green, blue or yellow. So to call it colour vision deficiency would be much appropriate, and it hits men more often than women. In a report by Prevent Blindness America, it is revealed that about 8% of males and less than 1% of females are affected with colour vision problems. Generally, red and green colour deficiency is the most commonly found. In very rare instances, a person may carry a trait which lessens his ability to distinguish between blue and yellow colours. This blue-yellow hue insufficiency normally is found in men and women equally.
Understanding signs and symptoms: Do you have any difficulty in seeing yellow, green or red colours? Do people often tell you that you are seeing the wrong colour? If so, then these are key signs that you are affected with a colour perception deficiency. Quite opposite to popular belief, hardly a colour blind person is able to see only the shades of gray. Most people who are deemed as colour blind are able to see shades but cannot distinguish between one colour and another and get easily confused with other shades, depending on the kind of colour blindness they are affected with. If you have suddenly developed a colour vision deficiency when you were able to view and distinguish all the shades previously, then you should visit an ophthalmologist without further delay.
Causes behind colour blindness: Colour blindness takes place when the light-sensitive cells within the retina stop responding accurately to variations in wavelengths of light.
Photoreceptors present in the retina are termed as rods and cones. Rods are present abundantly, and about 100 million rod cells are present in human retina and these cells are very sensitive to light, but rods are impervious to sunlight and therefore, are incapable of perceiving colours. The cones, on the other hand, are responsible for our understanding of different colours. There are three types of cones, each of which is responsible for perceiving red, green and blue light. The three cones work together to help us see the whole range of colours. People who are colour blind usually have faults in a particular cone cell, which makes them unable to distinguish that particular shade.
Combatting colour blindness: Gene therapies are reported to cure colour blindness in monkeys, as per the reports of a study conducted by researchers of the University of Washington and Florida in September 2009. While early methods appear promising, gene therapy is not considered effective for human beings unless the treatments are verified to be safe.
Hence there is no effective means of curing colour blindness, but there are some strategies that may aid you to function better. However, if you are into graphic designing or anything that requires handling of different colours, then you will need professional help. The sooner you become aware of your insufficiency, the better you can compensate for it.
Some people also use contact lenses or eyeglasses that act as filters to enhance colour perception. If you are affected by this problem, make sure you visit an eye-care practitioner for detailed advice.
If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided.
Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others.
List of eye diseases caused by diabetes
- Diabetic retinopathy: when retina' s smallest blood-vessels get severely damaged due to increased blood-sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.
- Cataract: Fogging or clouding condition can bring this kind of condition, and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day by day. Glared or blurred vision is the commonest symptom in this regard.
- Glaucoma: When the eye-fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others.
- Diabetic macular-edema: This eye disease mainly occurs in the advanced stage of diabetic-retinopathy. Macula is nothing but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed.
- Blurry vision: Though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.
Variety of contact lenses is used to correct refractive errors. Soft Contact (hydrogel) Lenses are most often used in various types of refractive errors but they have certain disadvantages. These lenses do not permit adequate Oxygen to pass through which is essential for health of cornea and hence they can be worn for limited hours, i.e 6 to 8 hours maximum and never while sleeping. The tear proteins get deposited on these lenses which limit their life to about a year. If worn for prolonged period or proper measures not taken to clean the lenses, cornea can get an ULCER which at times can result in permanent loss of vision. Disposable daily wear lenses provide safer alternative but the cost increases significantly. Since soft contact lenses are applied after cleaning with a solution which can be the cause of mild to severe allergic conjunctivitis which can become intolerable. Soft contact lenses are not ideal in eyes with high corneal astigmatism.
Merits of soft contact lenses are that they can be dispensed over the counter or purchased on line though it is not ideal. A correct curvature and power of a contact lens is determined by a contact lens specialist/ Ophthalmologist after measuring exact corneal curvature and using trial contact lens. Another merit is that these lenses can be accepted very easily since even on the first day they do not produce much of discomfort. These lenses can be worn off and on without any inconvenience. Recent introduction of Toric Contact Lenses have made them more acceptable in cases of moderate corneal astigmatism.
BREATHING CONTACT LENSES
These lenses are the one which permit significant amount of oxygen to pass through and hence can be worn for prolonged interval without any adverse effect on the cornea. These are of two types
1 Semisoft or Extended Wear RGP Contact Lenses
These lenses are made up of FP 92 which is a semi rigid soft plastic and is highly permeable to oxygen. These lenses are excellent for high refractive errors, especially in patients who have high corneal astigmatism. Even cases with irregular cornea or Keratoconus, these lenses can be accepted with rewarding results.
These lenses can only be fitted by an expert Ophthalmologist since precise measurement has to be carried out and various trial lenses have to be tried to evaluate the optimum fit. The lenses are made to measurement and the patient has to be precisely trained to fit the lenses and maintain them. As stated, the lenses can be safely worn while sleeping and there is practically no danger of corneal toxicity or infection. These lenses may last for 4-5 years. One of the demerits of these lenses is that they take 5-6 days to adopt and the patient is advised to use them regularly. They are excellent alternative to LASIK surgery.
2. SILICON HYDROGEL CONTACT LENSES
These are recent introduction of extended wear contact lenses with capacity to 'breathe' better than soft or hrdrogel contact lenses. Some of the recent Silicon Hydrogel Contact lenses introduced by Alcon and Bausch and Lomb can be worn for a week or so.
Silicon hydrogel lenses though indicated for prolonged wear but can cause mild keratitis and sometimes allergic keratitis if worn overnight. These lenses still needs lot of improvement to be free of complications
Advise: It is ideal to consult an Ophthalmologist specialized in contact lenses for fitting of a proper contact lenses. Advertised lenses some time misguide and can be damaging to the eye.

There are a number of eye conditions that make the use of glasses and eye lenses mandatory for a more comfortable life where your vision is as normal as is medically possible. Poor eyesight and conditions like inward eyelids and others can lead to the prescription of contact lenses and glasses. Contact lenses are delicate optical tools that glide easily over your eyes and need a lot of care. One should also know how to wear them properly. If one does not wear and care for the contact lenses properly, it may lead to a variety of complications. Read on to know how you can take better care of your contact lenses.
Cleanliness: To begin with, keeping the lenses clean is of utmost importance. Since these lenses will go on to the eye and remain there for most part of the day, it is imperative that they should be clean so that no dirt comes to settle on the eye to cause complications and even possible infections in the long run. While the disposable soft contact lenses do not need a whole lot of care as they can be disposed as and when the wearer needs a new pair, the soft lenses are the ones that need regular care so as to avoid vision affecting problems in the long run.
Clean Hands: Before you handle the contact lenses, you must wash and clean your hands thoroughly with a non cosmetic soap that is free of additives like fragrances and artificial perfumes, oils and other lotions. These may get transferred to the lens which will leave you with blurry vision. Dry your hands properly using a lint free towel.
Makeup: If you have to wear makeup, we would suggest doing so after you have safely installed the contact lenses in your eyes. Also, you must remember to remove your lenses before you begin the makeup removal procedure. This is to be done so that you do not get any makeup on to the delicate surface of the lens.
Disinfecting Solution: When you buy your contact lenses, you will also get a disinfecting solution as well as a set of instructions for taking care of your lenses. So ensure that you use the correct disinfecting solution, eye drops as well as the prescribed enzymatic cleaners to keep your lenses clean and free of germs with a light rubbing action. Let the lenses stand in this solution at night too so that the germs cannot travel to the surface.
Never use tap water or your mouth to clean these lenses as the microorganisms found even in distilled water can latch on to the surface.
Any patient who needs to undergo cataract surgery must be evaluated in a thorough manner so as to establish the requirement, appropriateness, expected surgical problems, expected benefits and co-morbid conditions having an influence on cataract surgery.
The preoperative assessment consists of -
A test for your existing glasses prescription:
It is useful for your cataract surgeon to know your existing glasses prescription in cases where there is a high refractive error (people who are very short or long sighted), in order to plan to correct this error after cataract surgery.
A full ocular examination: This includes looking at:
- The eyelid anatomy and inflammation.
- The state of the tear film, dry eye changes could make surgery difficult
- The presence of abnormalities in the cornea that could make visualisation of the cataract difficult during surgery.
- The amount of dilation the iris undergoes with dilating drops.
- The type of cataract. Soft cataracts can be aspirated. Hard cataracts need more ultra-sound energy and surgical time to break up and remove. White cataracts may need trypan blue staining to visualize the capsule
- The measurement of intra-ocular pressure. With this test, we aim to exclude glaucoma and ensure optimal control of immediate pre-operative and intra-operative eye pressures often with extra eye drops that temporarily lower eye pressure.
Biometry Tests: This is a simple pre-operative measurement. It calculates the correct power of artificial intra-ocular lens. They will be implanted into your eye once your cataract is removed.
Corneal Topography: This is a test to map out the corneal curvature in greater detail. It is used prior to premium IOL Implantation like Toric IOLS either monofocal or multifocal , to ensure avoid postoperative refractive errors. This extra test is only required if the biometry readings show larger than normal differences in keratometry readings.
Optical Coherence Tomography (OCT): This test allows detailed visualisation of the macula (the central sensitive part of the retina used for fine vision). If the ophthalmologist suspects any macula changes that may prevent a patient from visual improvement after cataract surgery, he always suggest optical coherence tomography.
Blood Pressure Measurements: It is very important to know your blood pressure measurements before your cataract operation. The risk of having a bleed at the back of your eye during cataract surgery (supra-choroidal haemorrhage) is very small (1 in 10000). But is higher if you have uncontrolled blood pressure.
Blood Sugar Measurements in Diabetic Patients: Cataract surgery itself does not affect your blood sugar measurements if you are diabetic. A routine checkup of blood sugars in diabetics before cataract surgery is done and the surgery if often delayed if the levels were greater than 20mmol/L as the risk of post-operative infection is higher.
Good eyesight can be an outcome of a diet rich in Omega 3 fatty acids and vitamin C. Including certain foods in your diet can be directly beneficial for your eye health and can improve your vision. Here is a list of 5 foods which will help you combat age-related vision problems and will supplement your overall eye health.
1. Eggs - Eggs are rich in vitamin A and lutein, which help you combat age-related vision problems and night blindness. Eggs are also beneficial for dry eyes and improving your eye health. Egg yolks are considered to be one of the best foods for your eyes and should be included in your regular diet. It also helps prevent age-related macular degeneration (AMD), which is one of the primary causes of blindness in the 60+ age group.
2. Leafy Greens - Leafy green vegetables like spinach and kale are rich in lutein and zeaxanthin which reduce the chance of cataracts. It is best to consume them raw as they have more antioxidants when uncooked. Other green vegetables like broccoli, collard greens, and zucchini are rich in lutein and play an important part in preventing age-related vision problems.
3. Carrots - Carrots improve your overall eye health as it contains vitamin A, the lack of which is one of the leading causes of loss of vision. The orange hue in carrots is due to Beta-carotene which helps the retina function better. Other foods rich in beta carotene are apricots, mangoes, pumpkin and cantaloupe which also contribute to healthy eyes. So make sure you include them in your diet.
4. Almonds - Almonds are rich in vitamin E, which prevents macular degeneration. Include a handful in your daily diet as it not only improves your eyesight but also effectively lowers cholesterol and prevents heart diseases. Nuts like pistachios and walnuts contain omega 3 fatty acids which contribute to the maintenance of your vision.
5. Citrus Fruits and Berries - Citrus fruits like oranges, grapefruits and lemons are rich vitamin C which reduces the risk macular degeneration and cataracts. Blueberries also aid in the protection of the retina from damage caused due to sunlight and oxygen.
