ABSTRACT
AlM To study an approach to visual acuity correction after intracapsular cataract extraction by phase - ll intraocular lens implantation through the individualized arcuate keratotomy. METHODS:
For demonstration, 48 postoperative patients ( 50 eyes ) receiving the intracapsular cataract extraction were gathered up. Each patient received a scleral tunnel major incision along the radial line of the maximum corneal refractive power determined by a cornea curvimeter, and a arcuate keratotomy was made opposite to the major one; through the major incision an iris-claw intraocular lens is implanted. Each patient was measured for their corneal astigmatism and uncorrected visual acuity before and after the surgery.RESULTS:
The results suggested the average corneal astigmatism before the surgery and that 3d, 1, 3, 6 and 12mo after the surgery as+3. 18±0. 68,-1. 56±0. 73,+0. 87± 0. 51, + 1. 21 ± 0. 70, + 1. 33 ± 0. 68 and + 1. 48 ± 0. 48 respectively. The uncorrected visual acuities 3d, 1, 3, 6 and 12mo after the surgery are 0. 5±0. 38, 0. 56±0. 23, 0. 55± 0. 24, 0. 52±0. 28 and 0. 51±0. 25 respectively. CONCLUSlON Phase-ll intraocular lens implantation witharcuate keratotomy is helpful to improve the postoperative visual acuity and reduce preoperative corneal astigmatism after the intracapsular cataract extraction aphakic eyes, lt is also a low-cost surgery, and easy to perform, with minor surgical injuries, particularly available for surgical visual acuity correction of the aphakic eye receiving intracapsular cataract extraction.
