Paper Abstract

Optimal keratoplasty (Opti-) is an improved method of laser thermal keratoplasty (LTK) that is performed using a continuous wave (cw) laser for anterior stromal heating together with a sapphire applanation window for epithelial protection. Opti-K has been used to improve uncorrected near visual acuity (UNVA) in emmetropic presbyopes while retaining or even improving uncorrected distance visual acuity (UDVA) - a truly optimal result that is linked to corneal multifocality produced by optimal keratoplasty. Opti-K has also been used to improve both UDVA and UNVA in hyperopic presbyopes. The safety and effectiveness of Opti-K have been evaluated in a Nassau clinical study and in an ongoing U.S. Clinical Trial. The procedure is noninvasive, simple, rapid, comfortable and repeatable. Although Opti-K VA improvements are temporary, treatments can be repeated whenever needed to maintain "vision rejuvenation".
