Small-diameter corneal inlay in presbyopic or pseudophakic patients

Abstract

We report the results of using the small-diameter corneal inlay to create a bifocal cornea. The inlay was implanted in five eyes in January 1993. At 12 months postoperatively, uncorrected near vision had improved from J4 to better than J2 in four of the five. The results indicate that the corneal inlay improves near vision and is compatible within the cornea.

Changes of the accommodative amplitude and the anterior chamber depth after implantation of an accommodative intraocular lens

“…There has not been found any correlation between the refraction power of the used 1 CU IOLs and their accommodative effect, based on the of a linear correlation (R 2 =0.005, linear model). [16]. None of these approaches has been able to attain actual accommodation; at best, multifocal intraocular lenses [1, 10, 27, 36] allow improved uncorrected near vision to the detriment of contrast vision [36], which limits their broad use in daily clinical practice even in the elderly.…”

Clinical evaluation of the Crystalens AT-45 accommodating intraocular lens

“…In the Crystalens AT-45 IOL group, 62.6% required an add of 1.5 D or less to achieve their monocular best corrected near acuity, whereas only 3.1% of the standard IOL group achieved their best corrected near acuity with an add of 1.5 D or less. degrees of success, including monovision, 6,7 implantation of corneal inlays, 8 and implantation of multifocal 9-11 and posterior chamber IOLs. Magnetic resonance imaging studies have established the continued functionality of the ciliary body with aging and demonstrated that the ciliary muscle retains much of its contractility in older patients.…”

Intracorneal Inlays for the Correction of Ametropias

“…In 1993, 5 eyes underwent implantation presumably with a Permalens lenticule in a freehand pocket, but the inlay dimensions and long-term outcome were not published. 28 There were other reports of this Permalens hydrogel being implanted in humans for the correction of hyperopia and aphakia. [29][30][31][32][33][34] In 1989, I personally received approval to implant 5 myopic hydrogels (Fig.…”
