Clinical Research Of The Implantable Collamer Lens For High Refractive Errors

Objective:To evaluate the effectiveness, predictability, security and stability of implantable collamer lens (ICL) or toric implantable collamer lens(TICL) for high refractive errors.Methods:This retrospective case series included 44 eyes of 26 patients withregular follow-up, after implantation of the ICLs or TICLs, the Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA), Dioptre,intraocular pressure(IOP),visual quality, slit lamp examination, corneal endothelium counting were evaluated at 1 day,7 days,1 month,3 months,6 months.Results:The patients were followed up for 6 months, all patients uncorrected visual acuity improved, have reached the level of preoperative best corrected visual acuity,18% of patients with uncorrected visual acuity even more than the preoperative best corrected visual acuity. The change of value of ICLs is within the normal range.IOP were to retreat back to the preoperative level. None of the patients showed a sustained high intraocular pressure. Follow-up of 6 months, the corneal endothelial counting change was not statistically significant. The rotation of some TICLs increases with time, but are within the acceptable range of patients.Conclusion:In terms of high refractive errors corrected, the ICL or TICL implantation can get a good visual quality. Surgical complications can be fully prevented and no serious complications.
