Modified scleral flap incision to reduce corneal astigmatism after intraocular lens implantation
1Zhongshan Ophthalmic Center, Sun Yat-sen University of Medical Sciences, Guangzhou, China.
Purpose:
To investigate a simple method during extracapsular cataract extraction with posterior chamber intraocular lens implantation in order to reduce surgically induced corneal astigmatism.
Methods:
A modified scleral flap incision was used in the extracapsular cataract extraction with intraocular lens implantation and the postoperative changes in corneal astigmatism was observed.
Results:
The peak value of postoperative corneal astigmatism was 3.60 D, and the corneal astigmatism regression was 2.11 D, surgically induced astigmatism was less significant in modified scleral flap incision group than that in conventional limbal incision group (P < 0.05).
Conclusions:
The modified scleral flap incision is an ideal incision for cataract extraction with intraocular lens implantation when phacoemulsifier is not available.
