目的评价轴性近视老年性白内障摘除及后房型人工晶体植入术的临床效果。方法对46例(56眼)老年性白内障施行巩膜隧道切口摘除,植入5.5mm PMMA硬性人工晶体。患者年龄为69.72±6.36岁,眼轴长为27.56±1.21mm,角膜曲率为43.38±1.36D,人工晶体屈光度为9.59±3.65D。结果术后1天裸眼或矫正视力≥0.5者,37眼(66.07%);术后1周、1个月及3个月分别为46眼(82.16%)、50眼(89.46%)及50眼(89.46%)。结论轴性近视老年性白内障摘除及后房型人工晶体植入术,具有术后视力恢复快、屈光状态稳定等优点,但眼轴极长者(>30mm),视力恢复较差。
Objective To evaluate the clinical effects of senile cataract extraction and posterior chamber intraocular lens implantation in axial myopia. Methods Forty-six eyes (56 eyes) of senile cataract were scleral tunnel excised and implanted with 5.5mm PMMA hard intraocular lens. The patient’s age was 69.72 ± 6.36 years, axial length was 27.56 ± 1.21mm, corneal curvature was 43.38 ± 1.36D, intraocular lens refractive power was 9.59 ± 3.65D. Results One month after surgery, 37 eyes (66.07%) had uncorrected or corrected visual acuity of 0.5 or more, 46 eyes (82.16%), 50 eyes (89.46%) and 50 eyes (89.46%). Conclusion The axial myopia of senile cataract extraction and posterior chamber intraocular lens implantation has the advantages of rapid visual acuity recovery and stable refractive state. However, the patients with extremely long axis (> 30mm) have poor visual acuity recovery.
