| Objective: To evaluate the effect of phacoemulsification with intraocular lensimplantation in patients with axial high myopia and analyze factors that influencethe postoperative visual acuity.Methods: Phacoemulsification with intraocular lens implantation was performedon 90 eyes of 52 patients with axial myopia from February 2005 to December 2005.It was divided into three groups according to ocular axial length, GroupI<28mm ,Group II 28～30mm, Group III≥30mm. Postoperative visual acuity,refractive power, fundus changes and operative complications were observed andthen compare the differences in postoperative visual acuity among three groups.Follow-up period was from four months to 10 months.Results: Both the naked visual acuity and best-corrected visual acuity improvedcompared with the preoperative status at the end of follow-up period. Thepostoperative visual acuity of Group I was better than that of Group II and GroupIII;Group II was better than Group III. However, the postoperative near visualacuity got worse and 2 cases (3 eyes) presented over-corrected. Eyes that maculawere damaged had bad visual acuity. Fresh retinal hemorrhage, macular edema,retinal detachment or posterior capsule rupture was not occurred. Posterior capsuleopacification developed in 9 eyes, without impact on visual acuity. 68 eyes werecomplained of vitreous floaters. There was no more complication in double eyesoperations which were undertaken in the interval of three days to two weeks,compared with single eye operation.Conclusion: Phacoemulsification with intraocular lens implantation is a safe andeffective way to treat cataract with axial high myopia. Postoperative visual acuity ismainly correlated to the operational skills, ocular axial length, fundus changes andchoose of IOL, as well as amblyopia. |
