Abstract:

To investigate the efficacy and safety　of posterior chamber implantable contact lens (ICL) implantation to correct high myopia in phakic eyes. MethodsUnder topical anesthesia   18 cases (32 eyes)  of high myopia were treated with posterior chamber intraocular lens implantation. Comparisons between postoperative uncorrected visual acuity and preoperative best corrected visual acuity, between postoperative refraction and preoperative refraction, and between postoperative intraocular pressure and preoperative pressure were carried out. ICL′s location and complications such as  cataract and secondary glaucoma were observed. ResultsPostoperative uncorrected visual acuity reached or exceeded the preoperative best corrected visual acuity in 18 cases (32 eyes). Except that 2 cases (2 eyes) had a transient high intraocular pressure 2 hours after the operation and 1 case had a high intraocular pressure 10 days after the operation, others were controlled normally. UBM showed that  there was a certain gap between ICL  and the lens. During the followup period, visual acuity, refraction, and intraocular pressure were stable. No complicated cataract, secondary glaucoma, retinal detachment or chronic meningitis, such as uvitis happened. ConclusionICL posterior chamber intraocular lens implantation in eyes is safe and reliable.
