Cataract surgery in Singapore is a very safe procedure, with more than 99% success rate. Having said that, any kind of surgery carries some risk even if very low. The risk of blindness is quoted at 0.0001% (approximately 1 in 10,000).
The main complications that may arise during cataract surgery are:
During the recovery period, it is usual for the eye to experience inflammation which may result in transient eye redness, eye swelling, changes in eye pressure or transient retinal swelling. These temporary effects can be treated easily with eyedrops or medication if detected early by your surgeon. Hence, it is important to continue regular follow-up checks after surgery.
In the long run, it is usual for the intraocular lens to accumulate tissue cells or opacification with time (1 to 5 years later). This is can managed with a simple office laser procedure which ‘polishes’ the lens to its original clear condition again.
The answer to whether one can go blind from cataract surgery in a word is yes. However, the likelihood of losing sight is very low. Cataract surgery is the most commonly performed elective surgery with success rates in excess of 95%. Serious complications include infections with rates as low as 0.01%.
Once done successfully, patients have their vision restored and their cataract problem permanently sorted. Occasionally, a layer of cells may grow on the back surface of the lens implant months or years after the surgery. This can affect the vision, giving the patient an impression that the cataract has returned when in reality it has not. This condition, known as posterior capsular opacification, can be easily solved with a 2-minute laser treatment.
