Patients should avoid driving for at least 24 hours after the surgery, largely due to effects from the anaesthesia, possible swelling affecting focus, and pupil dilation causing excessive glare. At the first post-operative check, the surgeon will usually assess whether vision is suitable for driving.
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.
If this does not help, surgery to remove the cloudy lens and replace it with an artificial lens is the only effective treatment. [1] Cataract surgery is not readily available in many countries, and surgery is needed only if the cataracts are causing problems and generally results in an improved quality of life.

There are three types of eye removal: [4] Evisceration – removal of the iris, lens, and internal eye contents, but with the sclera and attached extraocular muscles left behind; Enucleation of the eye – removal of the eyeball, but with the eyelids and adjacent structures of the eye socket remaining. An intraocular tumor excision requires an ...
Manual small incision cataract surgery (MSICS), which is considerably more economical in time, capital equipment, and consumables, but provides comparable results, is popular in the developing world. [6] Both procedures have a low risk of serious complications, [7] [8] and are the definitive treatment for vision impairment due to lens ...
It is rare in cataract surgery due to the use of prophylactic antibiotics. [30] Hypopyon occurs about 80% of the time. [21] Glaucoma may occur and may be very difficult to control. It is usually associated with inflammation, especially when small fragments or chunks of the nucleus access the vitreous cavity. [31]
Surgical options if the cataracts are bilateral and the vision is compromised include removing the affected lens of the eye and correcting the vision as early as possible so that the infants eyes can develop normally with visual stimuli. Some congenital cataracts are too small to affect vision, therefore no surgery or treatment will be done.
If a patient eventually develops a visually significant cataract, the PIOL will have to be explanted at the time of cataract surgery, possibly through a larger-than-usual incision. [citation needed] Another concern is progressive shallowing of the anterior chamber which normally occurs with advancing age due to the growth of the eye's natural lens.
