Eye Conditions


A cataract leads to reduced vision due to the lens in the eye becoming cloudy and opaque. If untreated this can lead to progressive vision loss and even blindness. Cataracts are quite common, especially as you get older. Other factors can also cause cataracts such as diabetes and trauma.


Cataracts are treated by replacing the opaque lens in the eye with a clear artificial lens. Modern advancements mean this surgery is usually carried with drops for anaesthesia and the surgery lasts about 15 minutes through a small incision of about 2mm. The surgery is bloodless and painless, with a quick visual recovery.

Mr Ratnarajan offers a bespoke service to all his cataract patients tailoring the surgery, anesthesia and lens choice to match your exact visual requirements. Mr Ratnarajan will guide you through the lens options best suited for you, which include monofocal, toric and mutilfocal lens. Highly precise measurements of your eye are carried out with a laser scanning machine to accurately predict the power of the replacement lens.


You will be guaranteed to see Mr Ratnarajan before, during and after your surgery. He will make this often nervy journey as comforting as possible through allocating enough time for you to answer all your questions and concerns.

What is Glaucoma?


Glaucoma is the leading cause of irreversible blindness in the world. It is caused by high pressure inside the eye, which leads to damage of the optic nerve that connects your eye to the visual centre in the brain.


Glaucoma affects your field of vision, normally in the periphery but central vision can also be affected. If untreated more and more vision is lost which can lead to irreversible blindness. Glaucoma can run in families so it is important to get checked if someone in your family has glaucoma.

Why does the eye pressure go up?


Clear fluid called aqueous is constantly being produced in the eye and is drained though a special membrane called the trabecular meshwork in the front chamber of the eye. In glaucoma the drainage is affected and so the pressure goes up.


Are there different types of Glaucoma?


There are two main types of glaucoma: open angle and closed angle glaucoma.


Open-angle glaucoma is the most common type of glaucoma in the UK. Eye pressure becomes high due to the drainage meshwork not working well enough to drain the fluid. Vision loss is often slow and painless so patients are not aware of the problem until the disease is already quite advanced.


Closed-angle glaucoma occurs when there is a blockage before the drainage meshwork. Eye pressure can rise quickly and can be accompanied with pain, blurred vision, haloes around lights, nausea and vomiting. This type of glaucoma requires prompt treatment to prevent rapid visual loss.

How is Glaucoma treated?


As damage from glaucoma is irreversible the key to treating glaucoma is early diagnosis. Treatment options include drops or laser initially with surgery usually reserved for more advanced cases. Laser for glaucoma is painless and effective and is now becoming used more and more as the initial treatment as people do not like putting eye drops which can sting or make the eye red. Mr Ratnarajan offers the latest glaucoma laser treatments to lower the eye pressure.


Glaucoma surgery is going though a period of innovation for which Mr Ratnarajan is leader in the field. Minimally invasive glaucoma surgeries (MIGS) are safer and more predictable and Mr Ratnarajan can discuss if you are suitable for these. These surgeries can often be combined with cataract surgery, only adding a few minutes to the surgery.
