What is IOL?
What is IOL?
Intra Ocular lens (IOL) is a tiny transparent convex lens. It is made of polymethyl methacrylate , (a harmless plastic substance).
Unlike contact lens, an IOL stays permanently in the eye and does not cause irritation.
Advantages of IOL:
- Since the lens is placed inside the eye, most often the patient need not wear glasses for clear vision. But sometimes patient has to wear glasses for clarity.
- Images are clear and of the same dimension without distortion
- Full vision returns very clearly
- Normal field of vision
New method with implanting of Intraocular lens (IOL) with sutures:
After administering a local anaesthesia, a 10 mm incision is made in the eye. The clouded lens is removed and replaced by an IOL and the incision is then closed with sutures. The entire procedure takes only 15 minutes.
Phaco or sutureless surgery with implantation of IOL
After giving a local anaesthesia, a 5mm incision is made in the eye. The cataract lens is broken into small pieces by a machine with ultrasonic waves and removed with a needle. A specially prepared IOL is inserted into the eye and the wound heals without sutures.
Advantages of Phaco
- Early surgery can be done, so that patient need not wait for the cataract to mature
- Small Incision
- No sutures and no need of suture removal.
- No irritation, no watering
- Early return to work
- No need to continue drops for a long time
- No need for hospital stay, Even if the patient stays, it is only for a short time
- Only one post-operative visit
- Stable refraction after one month
