Degeneration of rods in eyes with RP leads to night vision problems and loss of rod-derived cone viability factor (RdCVF) that is necessary for cone survival. Replacing RdCVF may prevent cone degeneration and loss of central vision.
Keratoneuralgia, also known as “pain without stain” is primarily a clinical diagnosis made for patients with corneal pain symptoms with minimal-to-no clinical signs and minimally, if at all, relieved by conventional dry eye treatments.
The Patient Reported Outcomes with LASIK-1 study shows LASIK surgery had excellent efficacy and safety, resulted in very high patient satisfaction, and was more often followed by improvements in dry eye and visual symptoms than worsening or new onset of these problems.
Pattern scanning laser trabeculoplasty uses computer guidance for precise delivery of laser spots to the trabecular meshwork. At 6 months post-treatment, percentage IOP reduction was similar in eyes undergoing PSLT performed with a 577-nm laser compared with selective laser trabeculoplasty using a 532-nm laser.
Preliminary results from the Patient Reported Outcomes with LASIK-1 (PROWL-1) and PROWL-2 studies show that at 3 months after surgery, more than 95% of patients are seeing 20/20 or better uncorrected binocularly and more than 90% have monocular uncorrected visual acuity of 20/20 or better, said Malvina B. Eydelman, MD.
