AIM: To evaluate the clinical effect of manual small incision combined with negative power intraocular lens implantation for cataract with high myopia.

METHODS: Totally 75 cases(98 eyes)with super high myopia and cataract which had underwent small incision combined with negative power intraocular lens implantation were studied retrospectively. Preoperative axial length and postoperative visual acuity, refractive diopter and expected deviation value(refractive deviation)were recorded. Eye conditions operation complications and postoperative were observed. The patients were followed-up for 6 to 12 months.

RESULTS: The mean preoperative axial length was 32.05±1.78mm. Best corrected visual acuity≥0.2 was in 66 eyes, accounting for 67.3%; ≥0.5 in 43 eyes, accounting for 43.9%; the postoperative refractive error <±1.00D was total 48 eyes, accounting for 49.0%; <±2.00D total 78 eyes, accounting for 79.6%. Intra-operative posterior capsular rupture occurred in 3 eyes. Intra-operative posterior elastic layer detachment occurred in 1 cases. The postoperative corneal edema was found in 21 eyes. Postoperative 6 months, posterior capsular opacification was found in 13 eyes, and the visual acuity recovered after Nd:YAG laser cut. No retinal detachment, secondary glaucoma, macular cystoid edema, intraocular lens shift and other complications were found. Two eyes had the symptom of binocular interference post-operation. Three months later, another eye was performed intraocular lens implantation. The symptoms were eliminated post-operation.

CONCLUSION: The manual small incision cataract extraction combined with negative power intraocular lens implantation for cataract with high myopia is safe, effective method.
