Purpose:
To determine the rate of stabilization of refractive error after temporal small incision phacoemulsification with insertion of an acrylic foldable intraocular lens (IOL) (AcrySof MA30).
Setting:
A university hospital anterior segment referral practice.
Methods:
The records of 100 consecutive patients with good visual potential having phacoemulsification with acrylic IOL implantation who had good visual acuity on the first postoperative day were reviewed. Refractive data at 1 day, 1 week, and 1 and 4 months were compared.
Results:
The mean spherical equivalent refraction was +0.31 diopter (D), -0.33 D, -0.51 D, and -0.35 D at 1 day, 1 week, 1 month, and 4 months, respectively. Cylinder by refraction was 1.17 D, 1.09 D, 0.96 D, and 0.99 D, respectively. From 1 week on, the cylinder power and axis did not differ significantly from that at 4 months. At 1 week, the spherical equivalent was within +/-0.50 D of the 4-month refraction in 66.1% of eyes and the cylinder was within +/-0.50 D in 72.9%. At 1 month, the corresponding values were 87.1% and 85.7%.
Conclusion:
The refractive error stabilized rapidly after temporal phacoemulsification with acrylic IOL implantation.
