Cataract, jise hum motiyabind bhi kehte h, ankho ki wo beemari hai jisme aankho k lense ki transparency dheere dheere kam hone lagti hai aur isse ankho ki roshni kaafi kam hojati hai. Iska ilaaj cataract surgery he hai. Isme koi dawaiya kaam nahi karti hai. Cataract surgery me ankho k defective lens ko nikal kar artificial lens laga dia jata hai, jisse hume fir se dikhna shuru hojata hai. Aaj kal cataract surgery ki latest technique ka naam Phacoemulsification hai. Isme hume ek chote se cheere se phacoe probe ko ankh k ander dala jata hai. Ye motiye k, yani cataract k defected lens k chote chote pieces ko pighla k bahar nikal deta hai. Aur fir usi cheere se artificial lens ankho k ander laga diya jata hai.
Jo lens ankho ke ander lagaya jata hai, use hum mukhya roop se 2 tarah se divide kia ja sakta h;
- Unifocal lens
- Multifocal lens
Unifocal Lens: Jese ki naam se pata lagta hai, unifocal lens ek point pe focus banata hai. Suppose, agar humara lens door k object pe focus bana raha hai to nazdeeki cheez saaf nazar nahi aegi. Aur agar pass ki object pe focus bana raha hai to door ki cheezein saaf nazar nahi aegi. Islie is lens ke sath hume chashma lagana he padega, jo ki hume patients ko pass ki nazar ka chashma lagana he padta hai saaf dekhne ke lie.
Multifocal Lens: Multifocal lens 2-3 jagah pe focus bana sakta hai. Aur iski madad se hume nazdeek or door, dono theek se dikhai de sakta hai. Lekin Multifocal lens has some disadvantages over Unifocal lens. like;
- Multifocal lens me hume image ka contrast kam milega in comparitive to Unifocal lens.
- Multifocal lens me Glare and Halos dikhai dene ke zada chances hote hai
Konse patients ko Unifocal lens chahie or konse patient ko multifocal lens chaie, ye patients khud decide kar sakte h, according to their choice and work. Jin patents pe operation se pehle he cylindrical number zada hota hai, un patients ko focus banane k lie aise lens ki zarurat hoti hai jinme cylindrical power ho. Aise lens ko hum Toric lens bhi kehte hai.
Yani ki aise patients k liye, Unifocal toric lens ya fir Multifocal toric lens he zada acche maane jate hai jinko ki wo choose kar sakte hai.
Cataract surgery k results aj ki tareek me bohot acche hai. Lekin ultimate visual gain after cataract after the sugery depends on the condition of the eyes before sugery and how the surgery works on the patients.

Patient Review Highlights
I was shocked to experience the symptoms of eye infection. I have consulted so many doctors , but no one was able to solve my eye infection. Even in case of emergency, the staff is always willing to help. A friend of mine referred to Dr Rajeev Gupta. He doesn't just randomly prescribes medicines, but first properly diagnoses the problem. I was amazed that other doctors before him were not able to even diagnose my problem, but he did it immediately and started the eye infection treatment for it.
i coud never have a oculoplastic surgery like this. I am almost my normal self post the treatment and for that Dr Rajeev Gupta is the reason. Both he and staff were very helpful. The lab in the Om Centre was very clean and well managed. He is not just friendly, but also is very motivating. In the very first sitting, Rajeev Gupta clearly told us the problem and the what the treatment procedure will be in future.

While spectacles are a fashion statement for some people, for others they are an uncomfortable necessity. Though contact lenses may be a little more aesthetically pleasing they too can be quite uncomfortable and cannot be worn throughout the day.
Thankfully, there is a third way to correct vision. Laser surgery or LASIK, it is a popular refractive procedure that can correct common vision problems, such as nearsightedness, farsightedness and astigmatism. This procedure aims at reshaping the cornea so that light entering the eyes can be focused onto the retina for the person to have a clearer vision.
Laser surgery is pain-free and quick in most cases. Usually, it does not take more than 15 minutes to correct vision in both eyes. The results of this surgery can be seen in as little as 24 hours.
The first step of laser surgery to correct vision is to create a thin, circular flap in the cornea. This is then folded back to access the stroma or underlying cornea. An excimer laser is then used to remove some of the corneal tissue. For people suffering from nearsightedness, the cornea is flattened while for people suffering from farsightedness, the cornea is made steeper.
In cases of astigmatism, an irregular cornea is smoothened. Once the correct gradient has been achieved the corneal flap is put back into place and the cornea is allowed to heal naturally. There are no stitches or bandages required in a laser eye surgery. You may feel a temporary burning or itching sensation in your eyes immediately after the procedure. It is important not to rub your eyes or place any pressure on them.
Your vision may also be cloudy or blurred for the first few hours. A doctor will usually advise you to rest for a few days after the surgery so that your cornea can heal properly. In a few days, your eyesight should stabilize, though, in a few rare cases, it may take a little longer. You should also avoid any form of strenuous exercising for a few days after the surgery.
Though LASIK surgery has a very high success rate, there are very rare occasions where spectacles may still be needed even after the surgery. Thus LASIK is a choice of treatment for many who seek freedom from glasses.

Antrior most transparent layer of the eye is called cornea. It is an extremely useful layer for refraction and protection of eye. Any trauma, foreign body or chemical etc can invade the integrity of this layer and can be invaded by bacteria, fungus or virus, resulting in the corneal ulcer. Sometimes, due to hypoxia induced by contact lenses too can result in a corneal ulcer.
Depending on clinical presentation, a doctor diagnoses the cause of the ulcer and start the therapy. Since the transparency of cornea is very important, a doctor starts very intensive therapy. With repeated frequent checkups if a proper and intensive therapy is not given, the ulcer can progress and can cause collection of pus in the anterior chamber which if not attended properly, can cause the infection to travel into the interior of the eyeball (vitreous chamber) resulting in total blindness. The ulcer can become deeper and lead to perforation of the cornea, causing severe damage to the eye and may require removal of pus (evisceration) or total removal of the eye ball.
Generally, fungal ulcers are more dangerous and occur mostly in rainy season.
- It is imperative that a case of corneal ulcer is diagnosed promptly and very intensive treatment proper treatment is given to save the disfigurement of the eye and total irreparable blindness.
- At times we have not only to give topical drops but oral therapy has to be given. Injections in the eye have to be given. Culture sensitivity has to be done in severe cases to identify the causative organism.
- In extremely severe cases, we have to perform, therapeutic keratoplasty.
Conclusion: Corneal Ulcer is a serious challenging problem with the potentiality to cause total and irreparable blindness and must be attended promptly by a very expert ophthalmologist to save the eye.

Headaches are common among working people as accumulated stress results in headaches and tiredness. Among the many different causes, strain on the eyes is one of the leading reasons for that annoying headache.
Taking an eye exam is recommended in case you are having headaches. The issues may not always be related to the eyes, but still a thorough eye check up is recommended. Strain in the eye is caused when small muscles present in the eye have to put in more effort than usual. Symptoms include aching, tired eyes with blurred vision and accompanying headaches. Such headaches are caused because of the following reasons:
The cornea is in abnormal shape and causes people to squint when they want to focus, and this leads to bad headaches.
This disorder is also called farsightedness. In case of this disorder, the images are focused by the eye behind the retina, and causes blurred vision and strain upon the eyes. Headaches occur as a result.
This kind of problem occurs when the lens hardens and becomes inflexible with old age. This makes it hard for a person to focus and causes sore eyes along with headaches.
All disorders or conditions of the eyes can be rectified with the use of prescribed spectacles and contact lenses. For people already having glasses, regular eye check up should be carried out. Your power may increase which you are unlikely to notice, so regular check ups are vital.
Headaches related to eye strain and eye problem can also develop from other causes. They are:
1. Glaucoma, an eye disease also causes headaches. This disease is characterized by the development of a fluid in the eyes, which in turn causes the internal eye pressure to shoot up. This pressure fluctuation can lead to headaches in many cases of glaucoma.
2. Cataract affected people suffer from headaches as well. Cataracts develop in individuals due to ageing. The lens becomes cloudy, and the vision gets blurred and slowly diminishes. The eye has to give more effort resulting in eye strain and accompanying headaches.
In case you are having headaches, and you are not being able to find out the reason behind it, you should have an eye check up. Eyes are very sensitive and added strain to them causes headaches. People who use computers for long hours are affected by headaches due to eye strain. The best prevention is to have an eye examination and switch to glasses or lenses if required.
Headaches are of various kinds and arise from different factors, but eye strain is known to cause a lot of headaches in people who do eye stress involving activities.

Even something as small as an eyeball, has multiple parts within it. The retina at the back of the eye ball is responsible for the clarity of vision. The central area of the retina is known as the macula. Macular degeneration is the deterioration of this part of the retina. Macular degeneration is age related and considered an incurable condition. People suffering from macular degeneration experience blurred vision, black spots and may eventually lose central vision while retaining peripheral vision.
There are two types of macular degeneration; wet and dry. The dry form of this disease is more common than its wet form. Of these, the latter causes more serious vision loss. Dry macular degeneration leads to white or yellow deposits on the retina leading to further degeneration. In the wet form of this disease, blood vessels beneath the retina start growing towards the macula and may pull it away from the base when they break or leak fluid.
There are three stages of age related macular degeneration (AMD).
- Early AMD
This is diagnosed by the presence of deposits on the retina. In most cases, ether is no vision loss at this stage but regular check-ups are essential.
- Intermediate AMD
A comprehensive eye exam will show the presence of larger deposits or pigment changes in the retina. At this stage, slight vision loss may be experienced.
- Late AMD
People suffering from late AMD have noticeable vision loss.
Though this disease is linked to aging, the exact triggers for macular degeneration are unknown. It is understood to be a combination of hereditary and environmental factors. The presence of certain genes and their variants has been associated with a number of cases of this disease. Studies also show that caucasions are at the highest risk of suffering from this disease. Depriving cells in the retina of oxygen can also increase a person's risk of contacting this disease. Other risk factors for this disease are obesity, smoking, high blood pressure and a light eye colour. The side effects of certain drugs can also induce this condition.
Macular degeneration is considered to be incurable but certain forms of treatment can improve vision and slow down the rate of deterioration. Treatment prescribed by a doctor depends on stage of the disease and whether it is wet or dry. Studies suggest that a diet rich in omega 3 fatty acids can prevent AMD and lower the risk of its progression.

Lazy eye or amblyopia is a childhood disorder wherein the child’s vision does not develop properly, especially in one of the eyes. If the condition is not treated at the very onset, it can lead to impaired vision in the concerned eye. As the child grows up, the brain will fail to pick up images from that eye.
This disorder is known to start when one eye has better vision than the other eye. An example would be if one of the eyes is affected by farsightedness (unable to see objects at a closer range) and the other is normal. In the case of a child, when the brain receives images from both the eyes, it will ignore the faulty eye’s image. When this situation repeats itself over months or years, it might lead to absolute deterioration of vision in the faulty eye.
Strabismus is another cause of amblyopia wherein there is a significant misalignment in the eye; one of the eyes may turn outward or inward. This does not allow the eye to focus properly on an object, thus leading to double vision. The brain again ignores the image from the faulty eye that causes vision deterioration in that eye.
The treatment begins by correcting problems in the affected eye and then putting a patch on the normal eye. Initially, the child may have difficulties adjusting to this new method, but bear in mind that it is absolutely necessary to wear the patch. The entire treatment process may range over a few weeks to even months. Regular visit to the doctor is of utmost importance.
In mild cases, an eye drop called ‘atropine’ may be prescribed for the good eye. The child may also require glasses to improve focus. In case of cataracts, a surgery might be needed to treat it.
The treatment should begin early, as it can get difficult to treat the condition once the child crosses his/her 7-8 year mark.
Macular Degeneration is an age-related macular degeneration incurable eye disease, which might result in blurred vision or no vision in the centre of the vision field, which might lead to visual distortions, reduced central vision, decreased intensity of the colours and can make it difficult for the patient to recognize faces, read, drive and to perform other activities.
Types of Macular Degeneration
1. Dry Macular Degeneration: It is characterized by the presence of drusen and thinning of macula because of a breakdown or thinning of the layer of retinal pigment epithelial cells in the macula.
2. Wet macular degeneration: In this type of AMD, there is an excessive growth of blood vessels, which causes bleeding, leakage, as well as scaring under the retina, which results in a rapid and severe loss of the central vision and might become permanent if not treated.
Causes of Age-related Macular Degeneration:
This is caused due to a problem related to the part of eye known as Macula, which is a spot at the centre of the retina of the eye. The focus point of the incoming ray of light is on Macula, which is responsible for see the things direct in front of us, especially reading and writing.
- Age: As the age increases, the probability of developing Age-related Macular Degeneration also increases significantly. The degree of the macular degeneration might vary person to person, but ageing is a major cause of suffering from age-related macular degeneration.
- Smoking: Smoking increases the chances of developing the disease in comparison to someone who does not smoke. The longer you have smoked, the more are the chances of developing it.
- Family History: The risk of developing the Age-related Macular Degeneration increases if it runs in your family, i.e. if your parents and siblings are suffering from it, then your chances of developing it are quite high as compared to the ones who do not have any family history.
- Obesity: The obese people have the higher chances of developing Age-related Macular Degeneration.
- Alcohol: Higher alcohol consumption also puts you at the risk of AMD, which is why one should always take alcohol in limited quantity only.
- Sunlight: As going out in sunlight without sunscreen is harmful to your skin, the same is harmful to your eyes for longer duration, and one should always wear UV-absorbing sunglasses to protect his eyes from AMD.
- Ethnicity: The white and Chinese are more prone to developing AMD as compared to the black people.
- Cardiovascular disease: the persons who have suffered diseases that affect the heart and other blood vessel are at higher risk of macular degeneration.
Treatment of Age-related Macular Degeneration
1. Anti-VEGF Drugs: The dry macular degeneration cannot be cured while the wet macular degeneration can be stabilized and maintained with a number of medical treatments to be injected into the eye, such as Lucentis, Avastin and Eylea. These are not long procedures and continued monitoring of the vision to maintain or improve the vision.
2. Laser photocoagulation: It consists of a concentrated beam of high energy thermal light that is directed towards the retina to obliterate and seal leaking blood vessels.
Uveitis is a set of inflammatory diseases that results in the swelling and damaging of the eye tissue. It can lead to temporary or permanent loss of vision. This disease often affects a part of the eye called the uvea, from which it has derived its name. It can affect people of all ages and can last from a short to long period of time. Ophthalmologists categorize uveitis into four major parts posterior uveitis, anterior uveitis, panuveitis uveitis and intermediate uveitis. This disease can be infectious or noninfectious, depending on the nature of the infection.
What causes uveitis and what are the major risk factors?
This disease is caused by the eye's inflammatory response and is caused by a series of potential factors such as the following:
- Immune system attack from the body
- Eye bruises
- Eye infection or tumor within the eye
- Foreign toxins that penetrate the eye
What are the diseases associated with uveitis?
Uveitis is associated with a range of diseases such as multiple sclerosis, Behcet's syndrome, Vogt-Koyanagi-Harada's (VKH) disease, psoriasis, herpes zoster infection, tuberculosis, rheumatoid arthritis, ulcerative colitis, toxoplasmosis, and cytomegalovirus (CMV) retinitis.
What are the typical symptoms of uveitis?
One or both eyes can be affected by uveitis. Some of the common symptoms include pain in the eye, light sensitivity and blurred and dark spots in vision. Moreover, the symptoms might vary from person to person and greatly depends on the type of inflammation. The symptoms also vary according to the type of uveitis.
What is the detection process?
The process of detection starts with a patient's medical history followed by several medical tests to rule out autoimmune disorders. This is followed by an evaluation of the central nervous system to rule out multiple sclerosis. Some of the other tests conducted by ophthalmologists include measuring the ocular pressure, slit lamp exam, funduscopic exam and visual acuity test.
The primary aim of the treatment is to eradicate inflammation, restore vision, prevent tissue damage and reduce pain. The treatment plan depends on the type of uveitis a patient displays. Doctors often suggest a dose of corticosteroid eye drops to arrest the infection in and around the eye. Other treatment methods include the prescription of immunosuppressive agents.
Furthermore, a doctor may suggest steroidal medication in the form of an eye drop, pill or injection. It can also be surgically infused into the eye. Some other agents used for treatment are azathioprine, methotrexate and mycophenolate. Medications such as these require regular monitoring of the blood to check for any side effects. Doctors also suggest biologics such as infliximab, rituximab, and adalimumab. Most of these drugs have a specific target in the immune system.
