How do cataract surgeries affect pre-existing ptosis?

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.

As with the cost of everything else, it is not surprising to pay double the amount for a similar service or product in Singapore compared to in Malaysia. This is largely due to the currency exchange rate. The other factors that could lower cost of cataract surgery in Malaysia would be the lower cost of surgical supplies, medical staff, rental or facility fee and medication in Malaysia. It is generally not recommended to have surgery done overseas as you may need unforeseen close monitoring or post-surgery care which would not be convenient if you need to travel for long hours so frequently.
