目的：研究白内障术中对前囊口采用预防性松解技术对术后囊袋收缩以及人工晶状体偏中心的影响。方法：选取年龄相关性白内障患者60例（84眼），记录术中撕囊直径。其中施行前囊口松解者44只眼（n＝44），未松解者40只眼（n＝40）。术后3个月、6个月复查裸眼视力、矫正视力、对比敏感度及眩光对比敏感度，测量前囊口直径、记录前囊形态，观察人工晶状体偏位及后囊混浊程度等。结果：术后3个月未松解组有4眼前囊口明显机化，囊口直径缩小1 mm。未松解组3眼前囊机化但无囊口缩小。2组人工晶状体均无明显偏位。昼无眩光状态下，在1．5c/d、12．0 c/d 2组之间CSF值差异有统计学意义（P＜0．05）。昼有眩光状态下，在1．5c/d、18．0c/d 2组之间CSF值差异有统计学意义（P＜0．05）。其余白天各空间频率及夜间所有空间频率2组CSF值差异均无统计学意义（ P＞0．05）。术后6个月未松解组有9眼前囊口明显机化，囊口缩小≥1 mm。松解组7眼前囊口明显机化但无囊口缩小。结论：术中预防性囊口松解技术可以减轻前囊收缩的程度，更久的维持人工晶状体的正位，提高昼无眩光状态下1．5c/d、12．0c/d，昼伴眩光状态下1．5c/d、18．0c/d空间频率的对比敏感度，改善术后视功能。
目的：研究白內障術中對前囊口採用預防性鬆解技術對術後囊袋收縮以及人工晶狀體偏中心的影響。方法：選取年齡相關性白內障患者60例（84眼），記錄術中撕囊直徑。其中施行前囊口鬆解者44隻眼（n＝44），未鬆解者40隻眼（n＝40）。術後3箇月、6箇月複查裸眼視力、矯正視力、對比敏感度及眩光對比敏感度，測量前囊口直徑、記錄前囊形態，觀察人工晶狀體偏位及後囊混濁程度等。結果：術後3箇月未鬆解組有4眼前囊口明顯機化，囊口直徑縮小1 mm。未鬆解組3眼前囊機化但無囊口縮小。2組人工晶狀體均無明顯偏位。晝無眩光狀態下，在1．5c/d、12．0 c/d 2組之間CSF值差異有統計學意義（P＜0．05）。晝有眩光狀態下，在1．5c/d、18．0c/d 2組之間CSF值差異有統計學意義（P＜0．05）。其餘白天各空間頻率及夜間所有空間頻率2組CSF值差異均無統計學意義（ P＞0．05）。術後6箇月未鬆解組有9眼前囊口明顯機化，囊口縮小≥1 mm。鬆解組7眼前囊口明顯機化但無囊口縮小。結論：術中預防性囊口鬆解技術可以減輕前囊收縮的程度，更久的維持人工晶狀體的正位，提高晝無眩光狀態下1．5c/d、12．0c/d，晝伴眩光狀態下1．5c/d、18．0c/d空間頻率的對比敏感度，改善術後視功能。

Abtsr act Objective:To explore the effect of preventative capsule edge release in preventing anterior capsular contraction and imtraoc -uler lens ( IOL) dislocation .Methods:The phacoemulsification and IOL implantation was performed on 84 eyes of 60 age-related cataract patients from March 2012 to December 2012 at our center with follow up in 3 and 6 months after the operation .The capsulorhexis size was recorded during operation .The postoperative monocular best -corrected visual acuity was equal to or more than 0.5 in long-distance.84 eyes were randomly divided into two groups:edge cutting group ( n=44 ) and none edge cutting group ( n=40 ) .The CSF and GFS was measured with OPTEC 6500 under distance vision conditions (with spatial frequencies of1.5c /d,3.0 c/d,6.0 c/d,12.0 c/d,18.0c/d). In addition, the morpha of anterior capsular ,capsule orifice diameter and location of IOL are also observed in the current study .Differ-ences and characteristics among groups were compared and analyzed .Results:In the day time without glare ,there was a significant differ-ence in CSF between edge cutting group and none edge cutting group at 1.5c/d、2.0c/d(all P<0.05).While in the day time with glare, a significant difference in CSF was also found between the two groups at 1.5cd/、 18c/d(all P<0.05).There was no significant difference at all other spatial frequency between the two groups .Conclusion:Preventative capsule edge release was found to be effective in limiting the degree of anterior capsular contraction , and keeping the IOL in location much longer , and improving contrast sensitivity function .
