Introduction:The design of the study was to look consecutively at what are the prime influences on enhancements in laser vision correction related to the perioperative environment.Methods:A prospective consecutive series of 4,079 cases was reviewed from a single surgeon at a single surgical site. Patients were followed prospectively and were only included after at least two years of postoperative follow-up.Results:The series ranged in primary treatments of spherical equivalents (SE) from 0 to -12 diopters (D) with up to 4 D of cylinder. The preoperative average SE was -4.59±2.79 D and the cylinder average was -0.90±0.90 D. Uncorrected visual acuity (UCVA) prior to the enhancement was 0.63±0.23 (20/32) and post-enhancement was 0.99±0.20 (20/20). The top four influences on enhancements were presence of an opaque bubble layer (31.00%); dry eye disease (27.60%); history of ocular allergy (24.10%); and poor fixation (17.10%). Patients could have more than one of the above influences.Conclusions:Laser platforms, outcomes analysis, nomograms, and other influences will be discussed to help produce enhancement rates below 1.00%, which for this series was 0.71% overall.

Purpose: We evaluated the refractive visual outcomes and efficacy of Transepithelial Photorefractive Keratectomy (TransPRK) using Smart Pulse Technology with static and dynamic cyclotorsion and the AMARIS 1050 Hz RS laser platform from Schwind in the eyes after a refractive lens exchange. Setting/Venue: Aurelios Augenlaserzentrum, Recklinghausen. Methods: We retrospectively evaluated the data of 552 consecutive eyes treated with refractive lens exchange between 2016 and 2019. A total of 47 eyes (8.5%) required a touch up after the clear lens exchange. From 43 eyes of 43 patients, we obtained a minimum follow up of 3 months. In all cases, we performed a TransPRK with a minimum optical zone of 7.2 mm, centering the ablation on the vertex of the cornea. Results: The average age of the treated eyes was 57 years old, with a range between 48 and 68 years. The mean treated sphere was 0.42 diopters (D), with a range between −1.0 and +1.75 D. The mean astigmatism was 1.06 D. Postoperatively, after laser vision correction, we reduced the sphere to a mean of 0.11 D (range −0.5 to +0.75 D), and, postoperatively, the mean astigmatism was 0.25 D (range −0.75 to 0 D). The predictability for a spheric equivalent (SEQ) of 0.5 D was 91%, and for 1 D it was 100% of the cases. No eye lost more than one Snellen line. Conclusions: TransPRK with smart pulse was predictable for correcting ametropia after Clear Lens Surgery.
