Cataract Surgery

Monofocal lenses provide sharp vision at one distance and are most common, but you will need reading glasses. Multifocal and trifocal IOLs correct near, intermediate, and far vision but may cause halos at night. Extended depth-of-focus lenses provide a smoother range with fewer side effects. Toric versions correct astigmatism simultaneously.

About 20% of patients develop posterior capsule opacification (PCO), where the membrane behind the implanted lens becomes cloudy weeks to years after surgery. It is treated with a YAG laser capsulotomy, a painless 5-minute procedure, with 83-99% of patients reporting improved vision. This typically only needs to be done once per eye.

Once your natural lens is removed and replaced with an artificial intraocular lens, the cataract cannot return — results are permanent. The artificial lens does not degrade, cloud, or need replacement. The only related issue is posterior capsule opacification, which is easily treated with a quick laser procedure.

Most ophthalmologists clear patients to fly 3-5 days after uncomplicated cataract surgery, once the first follow-up exam confirms no complications. Cabin pressure changes do not affect standard cataract surgery, unlike retinal procedures. Plan your trip for at least 5-7 days to allow for pre-op assessment, surgery, and the initial follow-up visit.

Look for centers with ISO 9001 or JCI accreditation, modern diagnostic equipment (OCT scanner, IOLMaster biometry), a surgeon who has performed at least 1,000 cataract procedures, and a transparent package that includes pre-op testing, the IOL, surgery, and at least one follow-up visit. Check whether they offer premium IOL brands available in your home country for easier follow-up.
