Objective: To evaluate the clinical effects of phacoemulsification and the negative power of intraocluar lens implantation in patients with extreme myopia and cataract.
Methods: 89 patients (126 eyes) received phacoemulsification and a negative power intraocluar lens implantation. Preoperative axial length, postoperative visual acuity and refractive error were recorded. Intraoperative and postoperative complications were observed. The follow-up time is from 6 to 25 months.
Results: The mean preoperative axial length is 32.45 mm. Best corrected visual acuity achieved 0.2 or better in 106 eyes (84.1%) and 0.5 or better in 69 eyes (54.8%). Of the 126 eyes, 56.3% were within 1.00 diopter (D) of refractive error and 90.5% were within an error of 2.00 D. Only 1 eye has posterior capsule rupture. 28 eyes had binocular disturbances. 15 eyes developed posterior capsule opacification and 6 eyes were performed neodymium: YAG laser posterior capsulotomy. No retinal or choroidal detachment or pressure improvement was seen during the follow-up.
Conclusion: It is safe and effective for extreme myopia with cataract to implant a negative power intraocular lens after phacoemulsification.
