ABSTRACT
Our objective in this retrospective case series was to report 4 cases of hydrophilic intraocular lens (IOL) opacifications after repeated intravitreal bevacizumab injections. This is a retrospective analysis of all the cases of IOL opacifications presenting to a tertiary referral ophthalmic center in Beirut between January 2013 and January 2019. Four cases were included in the study, of which one was treated for vitreal hemorrhage, the other for macular edema secondary to wet age-related macular edema, and the rest for macular edema secondary to diabetic retinopathy. The mean age of the patients was 71 years with a male predominance and a mean of 5 injections. The IOL opacifications appeared approximately 24 months after first bevacizumab injection. The opacification could be explained by multiple theories such as a possible anterior or posterior segment subclinical inflammation secondary to intraocular interventions, interaction between the hydrophilic properties of the IOLs and anti-vascular endothelial growth factor injection's content, impurities transmission during injection, or faulty IOL manufacturing.
ABSTRACT
PURPOSE: The purpose of this study was to evaluate the outcome of patients presenting with mild-to-moderate corneal haze after undergoing corneal collagen cross-linking (CXL) for keratoconus (KCN) and their response to a proposed standardized topical steroid-based treatment. METHODS: This study included 19 eyes of 14 patients presenting with corneal haze after undergoing CXL for KCN. Corrected distance visual acuity, corneal thickness and Kmax values by Pentacam® Scheimpflug tomography, as well as subjective corneal haze changes were evaluated before and after a topical steroid- and cyclosporine-based treatment. RESULTS: Visual acuity improved after the completion of the treatment by 0.043 logMAR (P = 0.017) and Kmax values decreased by 1.17D (P = 0.0024), while the corneal thinnest pachymetry remained stable. Data collected from the examiner's slit-lamp examination description revealed that seven eyes had a decrease in haze compared to 12 eyes with stable or no changes in the haze. CONCLUSION: Our findings suggest an improvement in visual acuity and possible corneal flattening with decreasing Kmax after the completion of topical steroids with taper course treatment in patients suffering from corneal haze post-CXL. This paper also highlights the importance of postcross-linking anti-inflammatory treatment and close follow-up.
