The refractive combination of high hyperopia with high astigmatism is difficult to treat surgically. In addition, there are not many suitable options to offer such patients presenting with this condition. The method used at the EYE Hospital Pristina using fresh lenticule implantation by ReLex-SMILE is safe and effective method. Fresh Corneal Implantation is a safe treatment for hyperopia with high astigmatism comparing with refractive IOL implantation (loss of accommodation, endophthalmitis). Its primary objective is to increase visual acuity, accommodation process, patient satisfaction which makes patient to enjoy a happier life. We believe this study will be the future of refractive surgery for treating high hyperopia.
The aim of this study is to assess visual and refractive outcomes after Toric Trifocal lens implantation and visual outcomes after laser vision correction (LVC) - ReLex Smile to correct residual refraction after 6 months of Toric Trifocal (IOL) implantation.
The purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn continuously for up to 1 week.
"GoCheck Kids" has added to its iPhone 7+ smart phone with flash concentrator a non-accommodating glow box fixation target. In pediatric eye patients, the "GCK" with glow box is compared to cycloplegic refraction as well as School Bus Accommodation-relaxing skiascopy, "2WIN" photoscreener and "Retinomax."
Compared to laser-assisted in situ keratomileusis (LASIK), Photorefractive Keratectomy (PRK) is associated with more discomfort and requires more downtime. However, it is oftentimes considered the preferred method of refractive surgery for patients with dry eye syndrome, high refractive errors, thin corneas, or those with more active lifestyles who may be more prone to dislodging their LASIK flaps. We hypothesize that the use of bandage contact lenses soaked in proparacaine will decrease pain levels compared to solely the use of bandage contact lenses after PRK.
Youth and some adults have photoscreening refractions and hand-held auto refraction before cycloplegia refraction during new and follow up eye examinations. Vector math is applied to each refraction to determine how closely the hand-held "dry" devices match actual refraction.
Randomized, bilateral, cross-over dispensing study of a standard and VR800 refraction and associated spectacle lenses.
The purpose of this clinical study is to assess the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in a daily wear modality with frequent replacement.
The current study aims to systematically investigate the diurnal variation in the optical quality of soft contact lenses on eye throughout the day. Subject reported quality of vision will also be evaluated.
