PURPOSE: To evaluate factors that infl uence retreatment results after primary hyperopic LASIK.METHODS: Restrospective study of 86 eyes of 61 patients that underwent LASIK to correct primary hyperopic spherical equivalent refraction and a second hyperopic retreatment due to undercorrection. All procedures were performed with the Technolas Keracor 217C excimer laser, lifting the preexisting fl ap for the retreatment. Preoperatively, under cycloplegia, mean spherical equivalent refraction of the series was ϩ3.05Ϯ0.99 diopters (D). RESULTS:At last follow-up, mean spherical equivalent refraction was Ϫ0.07Ϯ0.50 D. Effi cacy of the retreatment procedure was better when the primary LASIK attempted spherical equivalent refraction correction was Ͻϩ3.00 D (PϽ.05). Safety of retreatment was lower when attempted spherical equivalent refraction correction was Ͼϩ1.00 D (PϽ.05) and when attempted spherical equivalent refraction correction of both procedures combined was Ͼϩ4.00 D (PϽ.05). CONCLUSIONS:Effi cacy, safety, and predictability of retreatments secondary to undercorrection after primary hyperopic LASIK may be affected depending on the amount of diopters corrected in the primary procedure, in the retreatment procedure, and in both primary and retreatment procedures combined.

PURPOSE: To evaluate visual outcomes, satisfaction, and spectacle independence in non-presbyopic hyperopic patients who underwent bilateral refractive lens exchange with a trifocal intraocular lens (IOL) and to compare them with presbyopic hyperopic patients. METHODS: In this retrospective study, patients younger than 40 years underwent bilateral refractive lens exchange with a diffractive trifocal IOL (FineVision Micro F; PhysIOL SA) for hyperopia with at least 3 months of follow-up. A control group of patients older than 50 years was matched by axial length, sex, and follow-up. Safety, efficacy, predictability, patient satisfaction, and spectacle independence were evaluated. RESULTS: One hundred thirty-three patients (average age = 36.94 ± 2.91 years; range = 21.50 to 40 years) were included in this study. After a mean follow-up of 8.83 ± 5.69 months (range = 2.75 to 77.63 months), the safety and efficacy indexes and predictability within ±1.00 diopters (D) were 1.02%, 0.98%, and 99.62%, respectively, which was not different from the control group ( P > .05). No intraoperative complications were recorded. The only postoperative complication was posterior capsule opacification in 21 eyes (7.89%), which was similar to the control group ( P > .05). Ninety-seven percent of patients in each group expressed that they were satisfied and all of them in each group reported that they did not use spectacles for distance, intermediate, or near vision. CONCLUSIONS: Refractive lens exchange and trifocal IOL implantation for hyperopia in patients without presbyopia provided the same good visual outcomes as in presbyopic patients with a high rate of patient satisfaction and spectacle independence.

Ocular hypertension and traumatic endothelial cell damage could have been the causes of the syndrome. Although the IOP was not very high, previous LASIK could have led us to underestimate the IOP.

Purpose: Our objectives were to determine the anatomical and functional (visual and refractive) outcomes of corneal refractive surgery during breastfeeding and to compare the results with those of women who stopped breastfeeding at least 3 months before the procedure. We also evaluated predictability, safety, and efficacy indexes; number of retreatments; and adverse effects reported in babies. Methods: We performed a multicenter, retrospective, interventional case series review of patients who were breastfeeding and who underwent laser in situ keratomileusis or surface ablation (photorefractive keratectomy) from September 11, 2002 to December 12, 2017 (group 1, n = 142 eyes in the case group). Patients were compared with women who stopped breastfeeding at least 3 months before the procedure from September 11, 2002 to December 12, 2017 (group 2, n = 95 eyes in the control group). A total of 168 women (237 eyes) were included. Patients were incorporated consecutively. Functional (visual and refractive) and anatomical outcomes are described. Results: No significant intraoperative or postoperative complications were recorded. There were no significant differences between the groups in visual acuity, postoperative spherical equivalent, efficacy index, predictability, safety index, or retreatments. No infants experienced adverse effects. Conclusions: In our experience, laser in situ keratomileusis and photorefractive keratectomy can be performed effectively and safely in breastfeeding women.
