Canine cataract surgery involves small incisions in the cornea. The process is more intensive than in human cataract surgery, mainly due to the larger lens area in dogs than in humans which requires more power to break up the cataract, the need for general anesthesia, and post-operative care that involves anti-inflammatory medication and eye drops.
Following cataract surgery, side-effects such as grittiness, watering, blurred vision, double vision or a red or bloodshot eye may occur, and will usually clear after a few days. Full recovery can take four-to-six weeks. [35] Patients are usually advised to avoid getting water in the eye during the first week after surgery, and to avoid ...
Trief asks her patients to stop wearing soft contact lenses for one week prior to the pre-surgery measurements doctors take, since the lens can change the shape of the eye and affect the measurements.
Visual outcome after cataract surgery was close to conformity with WHO guidelines in Buenos Aires, where more than 80% of post-surgery eyes had visual acuity of 6/18 (20/60) or better, but ranged between 60% and 79% in most of the other regions, and was less than 60% in Guatemala and Peru. [126]
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.
This procedure usually takes less than 30 minutes in the hands of an experienced ophthalmologist, and the recovery period is about 2–3 weeks. After surgery, patients should avoid strenuous exercise or anything else that significantly increases blood pressure. They should visit their ophthalmologists regularly for 3 weeks to monitor the implants.
