2. Cyanopsia - Wikipedia

   en.wikipedia.org/wiki/Cyanopsia

   The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.

3. Multifocal intraocular lens - Wikipedia

   en.wikipedia.org/wiki/Multifocal_intraocular_lens

   The concept is based on the principle that the pupil tends to constrict for near tasks, so the central portion of the lens is designed for near and the outer portion for distance. For diffractive types of multifocal IOLs, light is split by diffraction and the vision is pupil independent.

4. Cataract - Wikipedia

   en.wikipedia.org/wiki/Cataract

   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'.

5. Cataract surgery - Wikipedia

   en.wikipedia.org/wiki/Cataract_surgery

   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.

6. Clear lens extraction - Wikipedia

   en.wikipedia.org/wiki/Clear_lens_extraction

   Procedure is similar to cataract surgery, most commonly followed by an intraocular lens implantation. In patients requiring only distance vision correction, a conventional mono-focal intraocular lens is placed in both eyes after the clear lens is removed. [1] While distance vision is fine in this, reading glasses are required for near vision. [1]
