Title

ASTIGMATIC OUTCOMES OF TEMPORAL VERSUS NASAL CLEAR CORNEAL PHACOEMULSIFICATION

Pages

  79-83

Abstract

 Purpose: To compare the astigmatic outcomes of PHACOEMULSIFICATION CATARACT surgery using temporal versus nasal clear corneal incisions.Methods: In a clinical trial, consecutive patients with senile CATARACTs underwent PHACOEMULSIFICATION and implantation of a hydrophobic acrylic foldable intraocular lens through a horizontal clear corneal incision (temporal in right and nasal in left eyes).Outcome measures included keratometric astigmatism and surgically induced astigmatism (SIA) calculated by the vector analysis method using the Holladay-Cravy-Koch formula.Results: The nasal and temporal groups consisted of 20 eyes each. Mean preoperative keratometric astigmatism was 0.63±0.48 D and 0.38±0.39 D in the temporal and nasal incision groups respectively (P=0.09). Data on 10 eyes in each study group was available for the six-month analysis. Mean keratometric astigmatism was as follows in the temporal and nasal groups respectively: 0.85±0.47 D versus 1.95±0.45 D at 1 week (P<0.001), 0.73±0.46 D versus 1.79±0.55 D at 4 weeks (P<0.001), and 0.63±0.30 D versus 1.05±0.56 D at 6 months (P=0.053) after surgery. SIA at the same follow-up intervals was 0.71±0.20 D versus 1.80±0.22 D (P<0.001), 0.63±0.20 D versus 1.65±0.31 D (P<0.001) and 0.26±0.46 D versus 0.92±0.36 D (P=0.002) in the temporal versus nasal incision groups respectively.Conclusion: Temporal clear corneal PHACOEMULSIFICATION induces significantly less astigmatism as compared to similar surgery using the nasal approach.
