How are cataracts removed?

Cataracts are removed using a procedure known as phacoemulsification. This means that an ultrasonic probe is used to emulsify (liquefy) the lens (phako is the medical term for the lens). The surgery is performed in an operating theatre using mild intravenous sedation. As the lens is a large component of the focussing of the eye it is replaced with an artificial lens called an intraocular lens (IOL).

Will the surgery be painful?

An anaesthetist will give a small amount of intravenous sedation so that there is no discomfort at all during the procedure. Patients are often concerned they will see the instruments coming closer to the eye but this does not occur. Overall, cataract surgery is not an unpleasant procedure for patients to undergo. Most patients have little recall of the procedure.

Most patients will not experience significant pain post operatively. Occasionally the eye may be uncomfortable overnight. The following day the eye will be examined and the patient will be given eye drops to be inserted four times each day for the next following two weeks.

What is an Intraocular lens (IOL)?

When a cataract is removed it is replaced with an intraocular lens implant. The exact power of the implant is calculated by Dr Troski and his staff at the preoperative consultation.

The decision regarding the power of the implant is made after measurements using an ultrasound measuring machine as well as an IOL Master, which uses a laser to calculate the length of the eye. Dr Troski uses a special computer program called the Holladay IOL Consultant to personalise each patient's implant power.

Types of Intraocular Lens implants

Dr Troski uses the most modern types of injectable intraocular implants, which are injected through a tiny incision that usually does not require a stitch. The implant types he uses corrects for distance vision (monofocal) or for both distance and near vision (multifocal). The decision regarding the type of implant is based on the patients requirements and wishes as well as the shape of the eye.

Can I have cataract surgery so that I won't have to wear glasses anymore?

Some patients who are extremely long or short sighted may have to wear heavy glasses which can cause visual distortion. Modern cataract surgical techniques can be used so that patients no longer have to wear these heavy spectacles. Dr Troski will explain these procedures and whether they will benefit you.
