We evaluated aphakia and pseudophakia in highly myopic patients whose axial lengths were 27 mm and over. Cataract surgery alone was performed on 99 eyes (aphakic group) and intraocular lens (IOL) implantation was performed on 84 eyes (pseudophakic group). The IOL power was determined by the SRK formula and ranged from +9.0 to +18.5 diopters (D). There was no statistical difference in postoperative complications between the aphakic and pseudophakic groups. The postoperative aphakic refractions ranged from +9.5 D to -3.5 D, and the pseudophakic refractions, from +2.5 D to -14.0 D. A visual acuity of 20/40 or better was achieved by 51% of aphakic patients and 63% of pseudophakic patients. A near visual acuity of 20/40 or better was achieved by 65% of pseudophakic patients. Seventy-three pseudophakic eyes (87%) were not corrected or were corrected with minus diopter lenses. This confirmed our opinion that there was no need to correct them for near vision. According to a postoperative questionnaire, 67% of the pseudophakic patients did not need spectacles for near vision and 93% of patients could see comfortably for daily life. In view of these results, we feel that most myopic patients are good candidates for IOL implantation.
我们评估了眼轴长度为27毫米及以上的高度近视患者的无晶状体眼和人工晶状体眼情况。仅行白内障手术的99只眼（无晶状体眼组），84只眼行人工晶状体（IOL）植入术（人工晶状体眼组）。IOL度数由SRK公式确定，范围为+9.0至+18.5屈光度（D）。无晶状体眼组和人工晶状体眼组术后并发症无统计学差异。术后无晶状体眼的屈光范围为+9.5 D至 -3.5 D，人工晶状体眼的屈光范围为+2.5 D至 -14.0 D。51%的无晶状体眼患者和63%的人工晶状体眼患者视力达到20/40或更好。65%的人工晶状体眼患者近视力达到20/40或更好。73只人工晶状体眼（87%）未矫正或用负度数镜片矫正。这证实了我们的观点，即无需矫正其近视力。根据术后问卷调查，67%的人工晶状体眼患者近视力无需眼镜，93%的患者日常生活中能舒适视物。鉴于这些结果，我们认为大多数近视患者是IOL植入的合适人选。
