Cataract FAQs

There are many known causes of cataracts including ageing, diabetes, certain injuries to the eyes, certain congenital disorders and certain metabolic disorder.

The actual implanting of the advanced technology IOL takes about 20 minutes, while the whole visit to the surgical center usually takes less than two hours. There is a sensation of pressure on the eye, but little or no pain. After surgery, more eye drops are applied to prevent infection, and decrease inflammation. A protective patch is usually placed over the eye. Once home, the patient should rest and avoid any strenuous activities. Be sure to arrange for someone to drive you home after the procedure.

Distance vision will usually be very good within a few days to a week after surgery. Return of near vision may take longer, as it usually requires more time to adapt to the multifocality of the lens. Some patients still require glasses or contact lenses with a mild prescription for optimal vision in extreme situations. This information is general and not intended to apply completely and specifically to any individual patient. The long-term safety and effectiveness of this lens has not been established.

The standard cataract surgical procedure is performed on more than a million eyes each year, and has proven extremely safe. However, there is always a chance of complication with even the most routine surgery. Most complications, such as minor infections, inflammation, and irritation, are temporary and easily treated.

Most patients require only a few days to resume normal activities, with some limitations and adjustments. Patients are given medications to prevent infection and control inflammation. A protective shield is advisable while sleeping; sunglasses can provide protection during the day. For several days after surgery, patients should avoid any heavy lifting or straining, which can increase pressure in the eye. Rubbing or pushing of the eye, and any situation that could result in being hit in the eye, are also to be avoided. When in doubt, the patient should consult their doctor or cataract counselors for guidelines regarding postsurgical activities.

In cataract surgery, natural lenses are removed and replaced with artificial lenses, which are not subject to deterioration and should last a lifetime.

The surgeon should perform the checkup on the day after surgery. The surgeon may approve subsequent checkups with another doctor after a consultation with that doctor to ensure familiarity with your case and appropriate care.

Glare, night driving problems, and light sensitivity can occur with both traditional and advanced technology lens implants. Night vision problems are usually much less severe than before cataract surgery. These phenomena are usually temporary and diminish as the brain and eyes adjust. All intraocular lenses can produce glare, light flares, or a halo effect at night, since the pupil is open wider and allows light to reflect off the edge of the implant. Your doctor can usually compensate for these problems through medication or night driving glasses.

Yes. For most people there is a period of weeks when your brain is learning to “see” up-close and at a distance with the new lens. This adjustment period is usually complete within 10 to 12 weeks.

IOL’s does not make the eye more susceptible to damage from trauma. Most injuries affect the cornea or the retina. If anything, the lens implant eliminates the chance of cataract due to eye trauma.
