Short-term effect of nd:yag laser capsulotomy on refraction, central macular thickness and retinal nerve fber layer thickness

Abstract

Objective: The aim of this study is to examine the effect of Nd: YAG laser capsulotomy on refraction, central macular thickness (CMT) and retinal nerve fiber layer (RNFL ResumoObjetivo: O objetivo deste estudo é examinar o efeito da capsulotomia de laser Nd: YAG na refração, espessura macular central (CMT) e espessura da camada de fibra nervosa retiniana (RNFL). Métodos: 42 olhos de 42 pacientes que trataram com capsulotomia laser Nd: YAG foram incluídos neste estudo prospectivo. O equivalente esférico (SE), a refração de potência cíclica, a espessura CMT e RNFL foram avaliados pré-operatório e no primeiro dia pós-operatório, primeira semana e primeiro mês pós-operatório. Resultados: valores equivalentes esféricos e valores de espessura macular central não alteraram significativamente no primeiro mês após o tratamento. Os valores médios e da espessura da camada de fibra nervosa nasal da retina aumentaram significativamente e a refração do poder cíclico diminuiu significativamente durante as visitas. Conclusão: Nd: a capsulotomia laser YAG é uma opção de tratamento confiante e confiável da opacificação da cápsula posterior (PCO). Após Nd: a capsulotomia do laser YAG, a refração do poder cíclico e os valores da espessura do RNFL mudam significativamente.

Effect of Neodymium: Yttrium-Aluminium-Garnet Laser Posterior capsulotomy on refractive status of the Eye

“…14 According to the study of Kim TG, Moon SW, in most cases Nd-YAG laser capsulotomy didn't change the refraction and only 7% of the eyes showed significant change in refraction. 15 Similarly in studies of Khambhiphant B and Kevher S, Nd: YAG laser posterior capsulotomy brought no change in spherical equivalents 16,17 but in a study of Sirakayaa E et al, a statistically significant change was noted in spherical equivalent after Nd-YAG posterior capsulotomy which is not supporting our study. 18 In the study of Oztas Z et al, changes were noted in anterior chamber depth, corneal thickness, and intraocular pressure but no change was noted in spherical equivalent.…”

Effect of Anterior Chamber Depth on the Development of Post YAG LASER Capsulotomy Macular Edema

“…Only surgical cutting or polishing had previously been feasible. 14 Two years following cataract surgery, the reported PCO incidence is 20.7 percentage; five years later, the reported PCO incidence is 28.5 percent. After phacoemulsification cataract surgery, vision loss is most caused by PCO (3) .…”

“…PCO can induce a decrease in visual acuity, sensitivity to contrast, and uniocular diplopia. 14 The advent of the Nd: YAG laser coincided with the switch from intracapsular to extracapsular cataract surgery, as well as the advent of phacoemulsification. The use of Nd: YAG lasers in the treatment of posterior capsule opacification has revolutionized the field.…”

Refraction and Intraocular Pressure Changes After YAG Laser Posterior Capsulotomy in Posterior Capsular Opacification

“…19 This procedure may cause increased intraocular pressure (IOP), injury or displacement of the intraocular lens (IOL), iridocyclitis, vitreous hemorrhage, and vitritis. 20 For capsulotomy, a Nd:YAG laser pulse duration of 2 or 3 nano-seconds with low millijoules (mJ) of energy is used to eliminate obstructions from one's eyesight. 21 This study based to assess the effect of Nd: YAG laser capsulotomy on Refraction, Cornea, Best Corrected Visual Acuity (BCVA), and Intraocular Pressure (IOP).…”
