During cataract surgery, the natural lens in the eye is removed and is replaced with an artificial lens. This sits inside the eye permanently and restores the focusing power. There are various techniques used for cataract surgery, and different techniques are used for different situations. Prior to the surgery various alternatives will be discussed.
Generally the surgery is done under local anaesthetic with some sedation. There is an anaesthetist present to ensure that the patient is comfortable and for patient safety. Afterwards the patient can go home and is seen the following day by the doctor. At this visit, the pad is removed and drops are commenced. Drops will be continued for about a month.
The intraocular lenses come in many different powers, and measurements are taken of the various parts of the eye. These are used to calculate the desired power for each patient. These lenses may correct myopia, hyperopia and astigmatism. Sometimes it is necessary to arrange a custom-made lens if a patient has an unusual eye. Patients have different expectations and requests regarding the final result and this will be discussed with you prior to the surgery. Our priority is for the patient to make an informed decision.
Generally the outcome of cataract surgery is very good, but as with all surgery complications can occur. These include inflammation, infection, dislocated lens and pressure rises. This will be discussed with you prior to the surgery.
Laser cataract surgery
A special type of laser called the femtosecond laser can be used to perform some of the initial steps in cataract surgery. This includes some of the cuts normally done manually and softening of a dense cataract. This can be helpful in particularly difficult cataracts, but is not necessarily helpful in all, nor does it necessarily give a better result in every situation. Our doctors will discuss with you what the most appropriate type of procedure is for your situation.
