Abstract:
The authors performed clear lens extraction on 22 eye to treat severe high myopia more than 12 diopters(D). The changes in spherical equivalent (S. E.), visual acuity improvement, and the complications were evaluated during 6 months postoperatively. A scleral pocket incision and continuous curvilinear capsulorhexis was made and lens extraction was performed via phacoemulsification and low power poserior chamber intraocular lens was implanted. The postoperative refractive error target were form -1.5D to-2.0D. More than 85% of eyes were within +/-1D of targeted refractive error. The posoperative uncorrected visual acuities were increased more than 20/200 in all eyes and 20% of eyes were increased more than 20/40 at postoperative two months. The postoperative corrected visual acuities were increased two or more limes in more than 80% of eyes. Intraoperatively, hyphema in one eye, wound leaking in two eyes and radial tear during contimuous curvilinear capsulorhexis in one eye were developed. Poltoperatively, retinal detachment in two eyes, subretinal neovascularization in one eye and posterior capsular opacification in three eyes were developed. In conclusion, the clear lens extraction was a effective method for correction of severe high myopia but longer follow-up of large number of cases is needed to fully assess the safety.
