A cataract usually forms in the eyes due to clouding of the naturally clear lens that coats the eyes.This coating is usually a matter of age advancement or any other injury that the eyes may have sustained. It may also be a birth defect that a baby may be born with. There are various ways to deal with this debilitating condition.
One of the methods of treatment includes cataract surgery. Read on to find out more about this form of treatment:
- Procedure: During this surgery, the ophthalmologist will remove the cloudy lens and clean it before replacing it with a man-made lens.The technique followed for this procedure is known as phacoemulsification which involves a small cut or incision for the cataract surgery. The incision helps the doctor in liquefying and then vacuuming the centre portion of the lens, which is slightly harder than the rest of the lens.
- Device: The doctor will usually administer anaesthesia first and then make the tiny incision on one side of the cornea. Thereafter, an instrument or device will be inserted through this opening to send out ultrasonic vibrations to the eye. These vibrations will help in breaking the lens into tiny pieces. These fragments will be removed with the help of a suction that will go in through the tiny cut. This cut may also be made with the help of a laser beam.
- New Lens: Once the fragments of the old lens have been cleared, the doctor will go about the process of inserting the new man made lens which is usually made up of clear plastic, acrylic or even silicon, and is known as IOL or intraocular lens. This process is generally termed as intraocular lens implantation.
- Improved Vision: With the help of the new lens, the patient will now enjoy better vision and a visible decline in the symptoms of the cataract including problems in night driving.
- Convenient: This procedure usually takes about an hour and is an outpatient procedure. It is a completely safe procedure where numbing drops are placed on the eye so as to reduce any pain significantly. The doctor will usually give you a novocaine injection around the eye. Also, cataracts from both eyes will not be removed on the same day, and the doctor will schedule you for cataract removal from the second eye for another day.
- Aftermath: After the surgery is over, it is normal to feel some amount of irritation in the eye. If this irritation is persistent, you must see a doctor about it.
Painkillers like acetaminophen and ibuprofen can be used to recover from the pain after the surgery. Ask an ophthalmologist about other measures.

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
- 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.
- 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.
Dry eyes are a common phenomenon that develops when the tears do not provide sufficient moisture to your eyes. This may also be the result of inadequate production of tears by the tear ducts. This condition cannot be cured permanently; however, treatments usually help.
Signs and symptoms of dry eyes:
1. A scratchy, stinging and a burning sensation in the eyes
2. Mucous surrounding the eyes
3. Sensitivity to light
4. Redness of the eyes
5. A feeling that something is stuck in the eyes
6. Problems in wearing contact lenses
7. Vision problems, especially while driving at night
8. Watery eyes caused due to the irritation that stems from dry eyes
9. Blurred vision
What are the causes?
1. Tears are a mix of fatty oils, water and mucus. This combination safeguards your eyes from any sort of infection in addition to keeping your ocular surface (the cornea surface) clear and smooth. Your eyes dry up if the tear ducts do not produce enough tears; medically, this condition is termed ‘keratoconjunctivitis sicca’. It can occur due to:
- Certain medical complications such as Sjogren’s Syndrome (a medical condition marked by dry eyes and a dry mouth) arthritis, diabetes, thyroid disorders and deficiency of Vitamin A among a few others
- Side effects of certain medications such as anti-depressants, acne medications, birth control medications and medicines to control high blood pressure
- Laser eye surgery or damage caused to the tear gland due to exposure to radiation or inflammation
2. Increased drying up or evaporation of the tears caused due to exposure to various kinds of smoke, dry air or wind, less of blinking while focusing on any particular activity or an object and eye lid problems such as in-turning of the eyelids (entropion) and out-turning of the eyelids (ectropion) can contribute to this irritating condition.
3. Imbalance in any of the layers constituting a tear film (made of oil, mucus and water) might lead to this condition. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

Eyes do more than we give them credit for and require more care than what we actually give them mostly. It isn't very difficult to ensure that your eyes are healthy and taken care of.
Here are 7 ways to care for your eyes everyday.
1) Splash water - Always clean your eyes with cold (filtered) water, from time to time. The clean water washes the eyes and keeps them healthy and free of diseases.
2) Don’t look into the sun - Never look into the sunlight directly. In fact, avoid looking at any sort of light that is harsh on the eyes. Direct rays of any kind of bright light can have damaging effect on the retina.
3) Get eyes examined - Have regular eye exams to check for diabetes and high blood pressure, if these health problems already exist in the family.
4) Do not smoke - People who smoke are more risk of having age-related eye problems.
5) Exercise your eyeballs - Roll the eyeballs up and down, and lift and right without moving your position. Repeat this exercise about 5 to 10 times. This helps relax the muscles in your eyes.
6) Distance eyes from screens - If you work on the computer, make sure there is enough distance between the screen and your eyes. Sit at least 22-28 inches away from the screen. The same applies while using smartphones and tablets. Do not view the screen from too close. Viewing the screen from too near as well as from too far; can increase the strain in your eyes.
7) Give them a break - People who work on the computer all day should ensure that they rest their eyes after regular intervals. Look in a long distance every few minutes.
