Refractive lens exchange with spherical diffractive intraocular lens implantation after hyperopic laser in situ keratomileusis

Abstract

Implantation of a spherical multifocal IOL after hyperopic LASIK was safe, effective, and predictable.

Visual quality after diffractive intraocular lens implantation in eyes with previous hyperopic laser in situ keratomileusis

“…These results agree with those in another study. 17 Under photopic conditions without glare, there were no statistically significant differences between the study group and the control group at any contrast level. With glare, the CDVA was significantly better in the control group than in the study group at 25.0% and 12.5% contrast; however, there were no significant differences between groups at 100% contrast.…”

“…Therefore, it seems logical that contrary to what occurs in patients with previous myopic LASIK, patients who have had hyperopic LASIK and then implantation of an IOL with a spherical design should have better visual function than those who have implantation of an aspheric IOL. A previous study 17 assessed the safety, efficacy, and predictability in eyes that had RLE with implantation of a spherical diffractive IOL after previous hyperopic LASIK; the results show the procedure to be safe, effective, and predictable. However, to our knowledge, there are no previous studies of the visual performance after spherical multifocal IOL implantation in patients with previous hyperopic LASIK.…”

“…Therefore, it is logical to think that in patients who had previous hyperopic LASIK, IOLs with a spherical design would provide better visual function than IOLs with an aspheric design, opposite to what occurs in patients who had previous LASIK for myopia. One study 17 found that refractive lens exchange (RLE) with implantation of a spherical multifocal IOL in eyes with previous LASIK for hyperopia was safe, effective, and predictable. However, to our knowledge, there are no studies evaluating the visual performance after spherical multifocal IOL implantation in patients with previous hyperopic LASIK.…”

Successful Restoration of Visual Acuity with an Extended Range of Vision Intraocular Lens after Multifocal Laser Ablation

“…Unfortunately, there are limited data available regarding successful visual restoration with PCIOL implantation in patients having undergone previous refractive laser surgery [1]. The few available published studies have been mainly performed by the same research group with the same lens models [2, 3, 4, 5]. To our best knowledge, nothing has been published on the use of accommodating, enhanced depth of focus and extended range of vision (ERV) intraocular lenses (IOLs).…”

Visual and optical performance with hybrid multifocal intraocular lenses

“…With regards to hyperopic LASIK patients, Alfonso and associates 99 carried out a prospective study to assess safety, …”
