Hydrodelineation is a method of separating an outer shell (or multiple shells) of the lens of the eye from the central compact mass of inner nuclear cataract (also called endonucleus) during a cataract surgery by the forceful irrigation of a fluid into the mass of the nucleus. [1]
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.
The intraocular lens did not find widespread acceptance in cataract surgery until the 1970s, when further developments in lens design and surgical techniques had come about. As of 2021, approximately four million cataract procedures take place annually in the U.S. and nearly 28 million worldwide, a large proportion in India.
Capsulotomy (BrE /kæpsjuː'lɒtəmi/, AmE /kæpsuː'lɑːtəmi/) [1] is a type of eye surgery in which an incision is made into the capsule of the crystalline lens of the eye. In modern cataract operations, the lens capsule is usually not removed.

Lens and cataract procedures are commonly performed in an out-patient setting; in the United States, 99.9% of lens and cataract procedures were done in an out-patient setting by 2012. [ 51 ] Topical , sub-tenon , peribulbar , or retrobulbar local anaesthesia is generally used, usually causing little or no discomfort.
