Excimer laser programming of refractive astigmatism vs. anterior corneal astigmatism in the case of ocular residual astigmatism (ORA)

چکیده
To determine whether manifest refractive astigmatism (RA) or anterior corneal (CA) is the best value for excimer laser programming in cases of ocular residual (ORA). Patients who had undergone LASIK surgery with a disagreement between and cylinder (ocular ORA) > 0.75 D were included retrospectively this study. We calculated target induced vector (TIA), surgically (SIA), difference correction programmed (DVRA), (DVCA) TIA SIA (DV), by Alpins method. Vectorial differences DV DVRA, DVCA, then to RA CA was closest ideal programming. Of total 104 eyes undergoing LASIK, 22 12 patients (21.1%) an ORA included. Mean 0.9 ± 0.2 mean postoperative subjective 0.45 D. The DV-DVRA 0.57 D, DV-DVCA 0.86 0.4 (P = 0.02). closer than correction. In discrepancy astigmatism, seems give better result.

LASIK for Spherical Refractive Myopia: Effect of Topographic Astigmatism (Ocular Residual Astigmatism, ORA) on Refractive Outcome
PURPOSE In eyes with a preoperative plano refractive cylinder, it would appear that there is no rationale for astigmatic treatment. The aim of this retrospective, cross-sectional data analysis was to determine the amount of topographic astigmatism in refractive plano eyes that results in reduced efficacy after myopic laser in situ keratomileusis (LASIK). METHODS This study included 267 eyes f...

Purpose. To assess the amount and the axis orientation of anterior and posterior corneal astigmatism after refractive lenticule extraction (ReLEx) for myopic astigmatism. Methods. We retrospectively examined 53 eyes of 53 consecutive patients (mean age ± standard deviation, 33.2 ± 6.5 years) undergoing ReLEx to correct myopic astigmatism (manifest cylinder = 0.5 diopters (D)). Power vector anal...

METHODS The study enrolled 64 pseudophakic eyes of 50 patients (71.8 ± 9.9 years old, mean ± standard deviation) who had undergone phacoemulsification with non-toric IOL implantation. Refractive astigmatism was measured using an auto ref-ker...
