TL;DR: The Prospective Evaluation of Radial Keratotomy (PERK) study is a nine-center, self-controlled clinical trial of a standardized technique of radial keratotomy in 435 patients who had physiologic myopia with a preoperative refraction between -2.00 and -8.00 diopters.

TL;DR: In the Prospective Evaluation of Radial Keratotomy (PERK) study, 793 eyes of 435 patients with 2 to 8 diopters (D) of myopia received a standardized surgery consisting of 8 incisions with a diamond-bladed knife set at 100% of the thinnest paracentral ultrasonic corneal thickness measurement and a diameter of the clear zone of 3.0 to 4.5 mm.

Polyethylenimine-conjugated gold nanoparticles: Gene transfer potential and low toxicity in the cornea
Ajay Sharma,Ashish Tandon,Jonathan C.K. Tovey,Rangan Gupta,J. David Robertson,Jennifer A. Fortune,Alexander M. Klibanov,John W. Cowden,Frank G. Rieger,Rajiv R. Mohan +9 more
TL;DR: In this article, the authors examined the gene transfer efficiency and toxicity of 2-kDa polyethylenimine conjugated to gold nanoparticles (PEI2-GNPs) in the human cornea and rabbit cornea in vivo.
Journal ArticleDOI
Targeted Decorin Gene Therapy Delivered with Adeno-Associated Virus Effectively Retards Corneal Neovascularization In Vivo
TL;DR: The clinical, biomicroscopy and transmission electron microscopy studies revealed that AAV5–mediated decorin gene therapy is safe for the cornea, and could potentially be used for treating patients.

TL;DR: The Prospective Evaluation of Radial Keratotomy (PERK) study as mentioned in this paper is a nine-center clinical trial of a standardized technique of radial keratotomy in 435 patients who had simple myopia with a preoperative refractive error between -2.00 and -8.00 diopters (D).
