Abstract. Purpose:To report the accuracy of SRK/T formula and stability of refraction after implantation of 4 types of acrylic intraocular lens(IOL). Cases and Method:This retrospective study was made on 237 eyes that received microincision cataract surgery during a 45-month period and that could be followed up for 2 months or longer after surgery. Eyes were ruled out that had visual acuity of 0.6 or less and that had astigmatism of ±1.0 diopter. Eyes were implanted with either of 4 types of acrylic IOL. Results:Difference between predicted and actual postoperative refraction was within ±1.0 diopter in more than 90% of eyes implanted with either type of IOL. The difference was independent of axial length. There were no differences between refraction one week and two months after surgery regarding each of 4 types of IOL. Conclusion:SRK/T formula is useful for each of 4 types of acrylic IOL. Postoperative refraction remains stable from early postoperative period.
