Phakic posterior chamber lenses for high myopia: Functional and anatomical outcomes

Abstract

Implantation of posterior chamber phakic IOLs is effective and predictable; however, long-term follow-up is needed.

Phakic intraocular lens implantation versus clear lens extraction in highly myopic eyes of 30- to 50-year-old patients

“…though the incidence appears lower with use of the V4 model of ICL. 17 In our series, the incidence was higher References than noted in another study, 15 …”

Phakic refractive lens implantation in high myopic patients

“…These results are even better compared with those of other posterior chamber lenses. [18][19][20][21][22] Few short-term complications were observed, such as IOP increase during the first postoperative day because of residual viscoelastic 23 and during the first month because of corticosteroid response. Corticosteroids were used to prevent postsurgery inflammation, but it might instead to avoid this steroid side effect.…”

Changes in the crystalline lens resulting from insertion of a phakic IOL (ICL) into the porcine eye

“…However, there is not always a correspondence between white-to-white and sulcus-to-sulcus, and indeed, it differs greatly between individuals. If a large-diameter lens is inserted, crystalline lens opacification tends not to occur [10], and did not occur with our 13.5-mm lens, but IOP elevation and effects on corneal endothelial cells remain a concern [2].…”

“…In Japan, a clinical trial of ICL (Staar Surgical, USA), a posterior chamber type of phakic IOL that can be inserted through a small corneal incision of 3.2 mm using an injector, was started in 2003. The currently anticipated problems include intraoperative crystalline lens damage [2,15], and, as postoperative complications, glaucoma [1,2,11,22], loss of corneal endothelial cells [2,6,7,22] and secondary cataract [4,10,11,15,22,24]. A trial of ICL in the USA showed a 2.1% incidence of secondary cataract [22].…”
