Posterior chamber phakic intraocular lens (ICL) for hyperopia: Ten-year follow-up

Abstract

The results confirmed the long-term safety, efficacy, accuracy, and predictability of ICL implantation for hyperopia. The Collamer material was well tolerated in all eyes.

New clinical pathways for keratoconus

“…67 Of the pIOLs available, 68 the Visian ICL (Staar Surgical, Monrovia, CA, USA) offers the longest safety track record for an injectable pIOL and is available in a wide range of powers (including toric correction up to 6D). Pesando et al 69 reported retrospective 10-year follow-up data in 59 ICLimplanted hypermetropic eyes, showing a mean endothelial cell loss of 4.7%, mostly occurring within the first few weeks of implantation and remaining almost unchanged thereafter. Edelhauser et al 70 reported prospective, multicenter, 4-year follow-up data on 526 eyes with a 2-3% cell loss rate over the first 3 years, followed by a cell increase of 0.1% between years 3 and 4, suggesting that endothelial remodelling and stability may have been achieved.…”

Comparison of clear lens extraction and collamer lens implantation in high myopia

“…49 Previous reports of posterior chamber phakic IOL surgery report an incidence of lens opacity from 1.5% to 25%. 23,50,51 Some of the variation may be due to the definition of cataract or opacity and the follow-up period, as well as surgical technique. In our series, lens opacity was noted in three eyes (11.11%).…”

“…16 Phakic intraocular implants can correct high myopia and hyperopia, with the advantages of reversibility, stability of the correction, and to a great extent, preservation of accommodation. 8,[17][18][19][20][21][22][23][24][25][26] An increasing number of procedures are being performed because of the expectation of a superior quality of vision obtained with phakic intraocular lens (IOL) implantation with respect to keratorefractive surgery for the correction of high ametropias. [27][28][29][30] However, induced cataract and glaucoma are at the heart of most concerns regarding these intraocular surgical procedures, especially for posterior chamber phakic IOLs.…”

Sixteen-year follow-up of hyperopic laser in situ keratomileusis

“…However, over the past quarter of a century, the introduction and refinement of excimer laser (7)(8)(9)(10)(11) , refractive lens exchange, multifocal (12) and phakic intraocular lens technologies (13) have heralded a new era in refractive surgery and offer promise for the correction of hyperopia. Published studies of hyperopic laser photorefractive keratectomy (H-PRK) and hyperopic laser in situ keratomileusis (H-LASIK) have demonstrated both efficacy and safety and such procedures are now in wide-spread clinical usage (7)(8)(9)(10)(11) .…”
