Usually after a cataract surgery an intraocular lens is implanted into the eye an intraocular implantation is a new system that can be placed the eye. It takes some time for the brain it recognize this new system. For so long a patient with cataract will be seeing hazy but soon after the intraocular lens is placed inside the eye vision becomes very clear. So it takes some time for the brain to adjust to the system, it may take a period of 1 day to a week’s time. Secondly depending in the type of cataract surgery, the vision recovery will take longer, even it is a small incision cataract surgery, the healing may take a longer time and the vison recovery will take atleast 10 days. If it is a phacomelulsification or a laser surgery the healing will occur very fast and the patient may be able to see clearly within 1 or 2 days. Also depending on the type of lens that is implanted in the eye, the visual recovery will depend. Suppose a person has gone in for a monofocal lens where he can see only one focus, where he can see the distance clearly, the vision recovery will occur within 2 to 3 days time but if the person has gone in for a multifocal or a trifocal intraocular lens where a person can see a distance, intermediate and a medium distance with the same lens, that takes a little longer time to heal or to recover because all images are formed in the brain in the same time. The brain has to adjust to ignore certain images and to see whatever is required. this may take a week’s time. Usually a person with a multifocal intraocular lenses is preferable to have both the eye cataract surgery within a short duration of time so that the patient can adjust to the new system and start seeing clearly. Depending upon the type pf the cataract surgery the visual recovery may last from 1 week to maximum of 10 days.
