改良巩膜瓣切口控制人工晶体术后角膜散光

MODIFIED SCLERAL POCKET INCISION TO CONTROL CORNEAL ASTIGMATISM AFTER INTRAOCULAR LENS IMPLANTATION

采用经改良的巩膜瓣切口在37例(37只眼)老年性白内障中进行白内障摘除及后房型人工晶体植入术,术后角膜散光峰值为3.60D,角膜散光回归为2.11D,与常规角膜缘切口比较,术后角膜散光显著减少.对改良巩膜瓣切口减少术后角膜散光的机理进行了探讨.

Modified scleral pocket incision was used on 37cases (37 eyes) with senile cataract when extracapsular cataract extraction with posterior chamber intraocular lensimplantation was performed.The peak value of postoperativecorneal astigmatism was 3.60 dioptor (D),corneal astigma-tism regression was 2.11 D.Modified scleral pocket incisioncould reduce significantly postoperative corneal astigmatismand promote to recover of visual acuity.The mechanism ofmodified scleral pocket to reduce postoperative corneal astig-matism is discussed.
