What is it about?

During the cataract surgery, one complication could be the implantation of the intraocular lens in an upside-down position. This occurs during the injection, and in many cases, regarding the possible complications that can happen when trying to reposition it, the lens is left in that position. In this paper, we study the optical quality variation when this happens, using a worst-case scenario: non-equibiconvex intraocular lens of high dioptric power.

We hope this article helps IOLs users (surgeons, optometrists, opticians, etc.) to expand their knowledge regarding the optical quality when the lens is implanted in an upside-down position. This may help to choose the proper IOL design prior to surgery, as well as understand that not all IOLs designs have the same optical behaviour when flipped.
