Purpose: To study the correlation between preoperative calculated IOL power and post operative refractive error in temporal phacoemulsification.
Materials and Methods: This study was a retrospective analysis in which data of 100 cases of senile cataract who underwent temporal phacoemulsification with foldable IOL was selected. Patients underwent post op examination at 4 weeks and only those patients whose vision was improving to 6/6 with or without correction was selected and their post operative refractive error in form of spherical equivalent was evaluated at 4 weeks of surgery and analysed with the preoperative calculated IOL power. All complicated cataract, cases with ocular pathology, patient with intraoperative or post operative complication and patient with history of any ocular surgery were excluded from the study. Formula used were SRK/T, HOFFER Q and HAIGIS.
Result: The mean IOL power used was20.39± 4.91, mean axial length was 23.43±1.53. The mean refractive error in form of spherical equivalent was-0.32±0.74. A total of 84 percent patients refractive error was upto 1D.A total of 37 percent patient had refractive error upto 0.25D, 57 percent upto 0.50 and 72 percent upto 0.75D.Myopic shift was present in 53 percent patients and hyperopic shift in 24 percent patient. There was no statistically significant correlation between iol power and refractive error at 4 week of temporal phacoemulsification as p value came as p=0.34
Conclusion: While pre op accurate calculation of IOL power is very important for better visual acuity post op but just looking at any IOL power we cannot guess about refractive error that it may result.
