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.
Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov , a Russian ophthalmologist . It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy , LASIK , Epi-LASIK and the phakic intraocular lens .
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'.
Cataract surgery in small animals such as dogs and cats is a routine ophthalmic procedure with a success rate of around 90%, and is usually better for eyes with relatively recent cataract development. The presence of other ocular problems may reduce the success rate. Procedures are similar to those for humans.
Possible Complications As with any surgery, evisceration may be complicated by bleeding, swelling, infection, and scarring. [ 14 ] Although these complications are rare, a doctor should be consulted regarding any pre-existing conditions or current medications that may increase the chance of surgical complications. [ 15 ]
Endophthalmitis is a serious infection of the intraocular tissues, usually following intraocular surgery complications or penetrating trauma, and one of the most-severe. It is rare in cataract surgery due to the use of prophylactic antibiotics. [28] Hypopyon occurs about 80% of the time. [8] Glaucoma may occur and may be very difficult to ...
Intraoperative floppy iris syndrome (IFIS) is a complication that may occur during cataract extraction in certain patients. This syndrome is characterized by a flaccid iris which billows in response to ordinary intraocular fluid currents, a propensity for this floppy iris to prolapse towards the area of cataract extraction during surgery, and progressive intraoperative pupil constriction ...
Limbal relaxing incisions (LRI) are a refractive surgical procedure to correct minor astigmatism in the eye. Incisions part way through the cornea are made at one side or at opposite edges of the cornea, following the curve of the iris, causing a slight flattening of the cornea in that area. [1]
