Vision Quality Questionnaire Assessment in Patients After Topography-Guided Photorefractive Keratectomy for Irregular Astigmatism Secondary to Radial Keratotomy

Abstract

Aim To evaluate the vision-related quality of life with the National Eye Institute Refractive Error Quality of Life (NEI-RQL) questionnaire in patients with astigmatism secondary to radial keratotomy surgery who underwent topography-guided photorefractive keratectomy. Methods Prospective non-randomized clinical trial. This study included 15 patients (30 eyes) aged > 21 years, mean age 55.1 (SD, 3.5) years, 53.3% female, with astigmatism ≤ - 6.00 D resulting from radial keratotomy, which could have been associated with hyperopia ≤ + 6.00 D. Photorefractive keratectomy with topography-guided custom ablation treatment was used in all cases. The patients answered the NEI-RQL questionnaire preoperatively and at 4 and 48 months after topography-guided photorefractive keratectomy. The following data were collected: age, sex and education level, pre-operative refraction data, visual acuity with or without correction, pachymetry, and keratometry. Results There was a significant difference between pre-and postoperative NEI-RQL scores for the domains clarity of vision, near vision, far vision, diurnal fluctuation, activity limitations, glare, symptoms, correction dependence, appearance, and satisfaction with correction (p < 0.001). Conclusion Topography-guided photorefractive keratectomy improved vision-related quality of life in patients with a history of irregular astigmatism secondary to radial keratotomy.

Comportamiento agronómico de líneas experimentales y variedades comerciales de soja (Glycine max, Fabaceae) en el Chaco central de Paraguay

“…Con respecto a la agricultura, el algodón (Gossypium hirsutum L.) es el cultivo principal, también se siembra maní (Arachis hypogaea L.) y sésamo (Sesamum indicum L.) y la soja ingresa como una alternativa para rotar con pasturas, en siembras a partir del mes de diciembre con las primeras lluvias, (Green Chaco, 2021;Harder, 2021). Los suelos agrícolas son cambisoles o inceptisoles, con textura limosa y moderados problemas de salinidad (Barboza et al, 1998;Piris da Motta Fleitas, 2020). El clima es semiárido cálido.…”

Laser vision correction after radial keratotomy: systematic review and meta-analysis

“…1,3,4 A relatively common concern in patients with a history of RK is residual refractive error and decreasing quality of vision over time. 5,6 Overcorrection or hyperopic shift associated with RK can be attributed to various factors such as cycloplegic refraction preoperatively, incision extension toward the limbus, increased depth or large incisions, longterm use of contact lenses, and eye rubbing or massage postoperatively. This progression can continue for years with increasing age.…”
