To evaluate the safety and efficacy of laser in situ keratomileusis (LASIK) to correct refractive error following cataract surgery.
The Eye Institute, Sydney, Australia.
This retrospective study reviewed 23 eyes (19 patients; 10 female, 9 male) treated with LASIK for refractive error following cataract surgery. The Summit Apex Plus and Ladarvision excimer laser and the SKBM microkeratome were used. The mean age was 63.5 years (range 50 to 88 years). The mean length of follow-up was 8.4 months (range 1 to 12 months) and mean interval between cataract surgery and LASIK was 12 months (range 2.5 to 46 months).
The mean preoperative spherical equivalent refraction (SEQ) for myopic eyes was -3.08 +/- 0.84 diopters (D) (range -4.75 to -2.00 D) and for hyperopic eyes was +1.82 +/- 1.03 D (range +0.75 to +3.00 D). The mean improvement following LASIK surgery was greater for myopic than hyperopic eyes (myopic, 2.54 +/- 1.03 D versus hyperopic, 1.73 +/- 0.62 D; P=.033). The percentage of patients within +/-0.5 D of intended refraction post-LASIK surgery was 83.3% for myopic eyes and 90.9% for hyperopic eyes and all eyes were within +/-1.0 D of intended (P<.001). The percentage of eyes with uncorrected visual acuity of 20/40 or better in the myopic group improved from none preoperatively to 91.7% postoperatively (P<.001) and in the hyperopic group improved from 27.3% preoperatively to 90.9% postoperatively (P=.008). No eyes lost 2 or more lines of best corrected visual acuity.
Laser in situ keratomileusis appears to be effective in correcting refractive error following cataract surgery. Longer-term studies are required to determine refractive stability.
评估准分子原位角膜磨镶术（LASIK）矫正白内障手术后屈光不正的安全性和有效性。
澳大利亚悉尼眼科学院。
这项回顾性研究对23只眼（19例患者；10例女性，9例男性）进行了评估，这些患者在白内障手术后接受了LASIK治疗屈光不正。使用了Summit Apex Plus和Ladarvision准分子激光以及SKBM微型角膜刀。平均年龄为63.5岁（范围50至88岁）。平均随访时间为8.4个月（范围1至12个月），白内障手术与LASIK之间的平均间隔为12个月（范围2.5至46个月）。
近视眼中术前平均等效球镜度（SEQ）为-3.08±0.84屈光度（D）（范围-4.75至-2.00 D），远视眼中为+1.82±1.03 D（范围+0.75至+3.00 D）。LASIK手术后近视眼中的平均改善程度大于远视眼（近视，2.54±1.03 D对远视，1.73±0.62 D；P = 0.033）。LASIK手术后屈光度数在预期屈光度±0.5 D范围内的患者百分比，近视眼中为83.3%，远视眼中为90.9%，所有眼睛均在预期屈光度±1.0 D范围内（P <0.001）。近视组中裸眼视力为20/40或更好的眼睛百分比从术前的零提高到术后的91.7%（P <0.001），远视组中从术前的27.3%提高到术后的90.9%（P = 0.008）。没有眼睛的最佳矫正视力下降2行或更多行。
准分子原位角膜磨镶术似乎在矫正白内障手术后的屈光不正方面有效。需要进行长期研究以确定屈光稳定性。
