Cataract Surgery


Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. Many patients' first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels. During cataract surgery, a patient's cloudy natural lens is removed and replaced with a synthetic lens to restore the lens's transparency.

What is Cataract?

Cataract is the opacification / milkiness of the natural lens of the eye. Due to this opacification , the patient would experience progressive loss of vision . When cataract matures to become absolutely white and opaque , there is total vision loss.

Types and Techniques of Cataract

Laser Cataract Surgery (Blade Free)

In Laser Cataract Surgery, major steps of cataract surgery are done with a computer controlled, highly efficient and Sophisticated Laser called FEMTOSECOND LASER.

The FemtoSecond Laser is the safest, most precise and most tissue friendly laser ever.

The most complication prone steps of cataract surgery are taken over by this Laser. So, we can assure perfection to all our patients in these steps of cataract surgery:-

    • Capsulotomy - The technique in which a small circular opening is made on the covering of the cataract affected Lens.

    • Lens Fragmentation - The technique in which the cataract is made into smaller pieces so that it is easily removed by suction.

    • Incisions - Removes a blade totally! The laser makes precise tracks through which the cataract is removed and an Intra Ocular Lens is implanted.

    • Astigmatism Correction - The precise Femtosecond Laser can make accurate treatment profiles for persons with astigmatism so that our surgeons can remove the cataract and also the astigmatism.

    • Bio-Optics - With Femtosecond technology, it is now possible to enhance vision even many months after cataract surgery in the rare event that some glass power remains.

    • Customizable - Implantation of a Restor Lens is possible so that the patient can be free of reading glasses for upto 90% of all normal tasks.



    Technique

    Cataract surgery is a common and relatively straightforward procedure that normally takes up to 30 to 45 minutes. It is usually carried out as day surgery under local anaesthetic, which means you are awake during the procedure and you can go home on the same day.

    The most common surgical technique used is known as Phacoemulsification

    Cataract Eye

    Before the operation, a nurse will put drops in your eye to dilate (widen) your pupil. A local anaesthetic will also be given, which can be applied as eye drops or given as an injection into the tissue around the eye.

    The surgeon then makes a tiny cut in your cornea (the transparent layer at the front of your eye). A small probe that emits ultrasound waves (high-frequency sound waves) is inserted through your cornea into the eye to break the affected lens into pieces. These pieces are then liquified and sucked out. A second probe sucks out the remaining soft pieces of outer lens.
