Macular pucker removal and repositioning of decentered IOL

Macular pucker surgery using 25 gauge small incision "no stitch" system and repositioning of decentered intraocular lens, This 67 year old white male has noticed decreased vision in his left eye for one year.

V sign in corneal transplantation

This video demonstrates the "V" sign during penetrating keratoplasty. The "V" sign occurs when the needle passes at 99% depth on the host cornea. Because descemet's membrane is elastic, it travels with the needle forming a V until the suture is passed and the V is released. Observing the V during surgery ensures that one is a the correct depth when passing sutures during corneal transplantation.

A great video with commentary discussing topical local anaesthesia in cataract surgery.
