Is clear vision guaranteed after surgery?

No surgeon in the world can perform a surgery with guaranteed results. However, almost all the patients regain good vision following cataract surgery.

The calibre of vision obtained after a successful cataract surgery with IOL depends upon the health of the retina behind. Eye disease or problems in the cornea, retina or optic nerve may limit the potential for clear vision even when the cataract surgery itself has been successful.

However, it might not be possible to evaluate the condition of the retina, optic nerve, in advanced cataracts.

Cataract and IOL surgery is not a magical procedure and need not necessarily restore normal vision immediately. Blurred vision may be present immediately after surgery. As the eye heals over a period of time, vision improves gradually.
