Refractive outcomes and safety of the implantable collamer lens in young low-to-moderate myopes

Abstract

PurposeTo evaluate visual and refractive outcomes and safety of implantable collamer lens (ICL) implantation in low-to-moderate myopia.SettingPrivate Practice – Dougherty Laser Vision, Westlake Village, CA, USA.MethodsA chart review was performed in 56 (104 eyes) consecutive patients who underwent implantation of the Visian ICL V4 model. Inclusion criteria were age between 21 and 40 years, spherical equivalent between −3.00 D and −10.00 D, and cylinder up to −5 D. Data on visual acuity, refraction, and complications were collected.ResultsThe mean time to the last postoperative visit was 13.1±14.0 months (range, 2 to 50 months). The mean preoperative spherical equivalent was −6.96±1.60 D and the mean preoperative cylinder was −1.03±0.88 D. The mean preoperative corrected distance visual acuity (CDVA) was 20/20 (range, 20/15 to 20/80) that remained unchanged at last postoperative visit. At the last postoperative visit, the spherical equivalent was −0.08±0.01 D and the cylinder was 0.29±0.71 D. Comparison of postoperative uncorrected distance visual acuity (UCDVA) to preoperative CDVA indicated that 27 eyes (26%) had better postoperative UCDVA and 61 eyes (59%) had UDVA equivalent to the preoperative CDVA. Postoperatively, 4 eyes lost 1 line of CDVA and no eyes lost >1 line of CDVA. There were 32 eyes that gained at least ≥1 of CDVA. There were no intraoperative complications. Postoperatively, 3 patients (6 eyes) had dry eye, and 1 patient complained of nighttime halos in 1 eye. At the last postoperative visit, there were no eyes with lens opacity or glaucoma.ConclusionICL implantation for low and moderate myopia up to −10 D in patients up to 40 years of age was safe, accurate, and efficacious. ICL implantation may be a good alternative to laser in situ keratomileusis for young myopes less than −10.00 D.

Implantable collamer lens with a central hole for residual refractive error correction after corneal refractive surgery

“…Previous studies have demonstrated that ICL V4c implantation for correcting moderate to high myopia 3 has good safety, efficacy, predictability, and stability after long-term follow-up [9][10][11] . Recently, ICL implantation has also been confirmed to perform well for low and moderate myopia [12][13] .These provide theoretical support and guidance for the use of ICL to correct residual refractive errors after corneal refractive surgery.…”

Efficacy, safety and stability of implantable collamer lens incorrection of high myopia

“…There is agreement between our results and results of Paul and Taylor who studied refractive outcomes and safety of the implantable collamer lens in young low to moderate myopes. Their study was retrospective study performed by chart review of (104 eyes) with 50 months follow up period (22). The study showed high efficacy , safety and stability of ICL during the follow up period .…”

Safety assessment of using collamer phakic implants in the correction of refractive errors

“…Podczas ostatniej kontroli lekarskiej po operacji sferyczny ekwiwalent wynosił −0,08 ±0,01 dioptrii, a cylinder 0,29 ±0,71 dioptrii. 13 Porównanie pooperacyjnej nieskorygowanej ostrości wzroku (ang. uncorrected distance visual acuity -UCDVA) z przedoperacyjną CDVA wykazało, że 27 oczu (26%) miało lepszą pooperacyjną UCDVA i 61 oczu (59%) miało UDVA odpowiadającą przedoperacyjnej CDVA.…”

“…Podczas ostatniego badania nie stwierdzono zmętnienia soczewki. 13 Gimbel et al przeanalizowali rezultaty wszczepienia Visian V4 ICL w oczach pacjentów krótkowzrocznych, okres obserwacji wahał się w granicach 2-14 lat. Wspomniane retrospektywne badanie wykazało, że odsetek rozwijającej się zaćmy przedniej podtorebkowej był dodatnio skorelowany z wiekiem.…”
