Angle-supported phakic intraocular lenses in hyperopia

Abstract

High hyperopia was corrected safely and predictably by an angle-supported PIOL with limited complications.

Metaanalysis of cataract development after phakic intraocular lens surgery

“…Although most studies excluded patients with preexisting cataract, some included patients with other ocular pathologies. 35,54,64,128,141 Subgroup Analysis of Angle-Fixated Anterior Chamber Phakic Intraocular Lenses There were 2 reports of angle-fixated AC pIOLs in both hyperopic and myopic eyes, 27,69 1 report in hyperopic eyes, 68 and 2 reports in presbyopic eyes 26,27 ; the remaining reports were in myopic eyes. Two studies were of bioptics.…”

“…In Stage 2, 310 articles were retrieved, 229 of which satisfied Stage 3 criteria; 123 articles eventually satisfied Stage 4 standards and were included in the study. There were 24 articles on AC pIOLs, 4,11,12,15,23,26,27,53,[56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71] 5 of which described previously published cases. 15,53,62,63,69 There were 50 articles on IF pIOLs, 3,6,[8][9][10]28,30,31,33,[35][36][37][38][39] 14 of which covered formerly published cases.…”

Optical Coherence Tomography of the Anterior Segment in Eyes with Phakic Refractive Lenses

“…To overcome these problems, the material was changed from PMMA to hydrophilic acrylate or hydrophobic acrylate. However, severe complications such as endothelial decompensation (Coullet et al 2007) and pupil ovalization (Leccisotti 2005) after implantation of an anterior PIOL have resulted in several European countries having recalled these lenses for the correction of refractive errors (Kohnen 2007).…”

Iridocyclitis associated with angle-supported phakic intraocular lenses

“…The prognosis is generally good, and IOL explantation is rarely required. 1,6 Excluding the exceedingly rare cases of bacterial endophthalmitis 14 and the uncommon case of undersized, movable IOLs, 8 its pathogenesis is unclear but most likely related to chronic iris-IOL contact, as observed with pseudophakic anterior and posterior chamber IOLs. [15][16][17] Haptic-angle interaction has been proposed as a possible mechanism, leading to an improvement of haptics in newer models 5 ; however, iris-fixated anterior chamber pIOLs (with no angular support) do induce a similar iridocyclitis in approximately 7% of eyes.…”

“…This IOL is released in 3 overall diameters of 12.5, 13.0, and 13.5 mm, in powers from C4 to C20 D, and with a total optical zone of 5.0 mm; the haptics are inversely z-shaped and posteriorly angulated at 14 degrees. 6 The IOL power was calculated by the van der Hejde formula. 7 The overall IOL diameter was calculated by adding 1.0 mm to the horizontal corneal diameter.…”
