The improvements in excimer laser technology made hyperopic excimer refractive surgery a valuable option for hyperopia correction. However, despite the good visual and refractive outcomes of excimer laser photorefractive keratectomy (PRK) and laser in situ Keratomileusis (LASIK) treatments, they are more effective and stable for the correction of low degrees of hyperopia than high hyperopia1-7....

Purpose: To evaluate efficacy, predictability and safety of the surgical correction of high myopia using the phakic posterior chamber implantable collamer lens. Design: A prospective, nonrandomized, non-comparative interventional case series. Participants: Twenty seven eyes of fifteen patients aged from 20 to 46 years having high myopia were included. Intervention: STAAR modified collamer impla...

BACKGROUND The aim was to evaluate the safety, efficacy, stability and predictability of posterior chamber collagen copolymer phakic intraocular lens (pIOL) implantation to correct myopia and myopic astigmatism associated with keratoconus. METHODS The unaided vision and visual acuity, refraction and adverse events were measured in 22 keratoconic eyes of 14 patients after using an implantable ...

PURPOSE To compare the efficacy and outcome of phakic toric implantable collamer lens (TICL) and refractive clear lens extraction with AcrySof Toric intraocular lens (TIOL) implantation for the treatment of myopic astigmatism. PATIENTS AND METHODS This study assessed eyes with myopic astigmatism >-1 D and ≤-4 D with a spherical equivalent >10 D or <10 D if the patients were unsuitable for cor...
