Abstract:Deterioration may occur after implantation for 10 years or longer. This is due to microstructural change of the hydrogel material. The most common problems are motility disturbance and presence of a tumor-like, palpable mass under the eyelid. Removal of the implant can alleviate some ocular problems. However, RD can recur and diplopia may persist after removal of the SB. Vision usually is not affected.
“…[9] Moreover a study by Chen et al carried out in 2012 aimed to analyze 23 patients after buckle removal and reported no visual acuity changes after buckle removal. [25] It is necessary to add that in the present study myopia was the most predisposing factor for RRD (13/15). The cause of the retinal detachment in other two patients was unknown.…”
Purpose:The present study aimed to evaluate refractive error and axial length changes after buckle removal due to buckle complications.Methods:A total of 15 patients involved in this study. The enrolled patients who had history of scleral buckling (SB) for rhegmatogenous retinal detachment referred to clinic for buckle removal due to buckle-related complications. Complete ophthalmic examinations and IOLMaster (Carl Zeiss) device performed prior and 3 months after buckle removal. Also best corrected visual acuity (BCVA), refractive error and axial length changes evaluated after buckle removal.Results:BCVA, refractive error, and axial length changes were not statistically significant (P value: 0.24, 0.23, 0.33, respectively). No redetachment or any other complication was observed after buckle removal.Conclusion:The study displayed induced globe shape changes due to SB are irreversible after buckle removal. In addition, it is a safe procedure and does not raise any risk of retinal redetachment.

“… 8 In a study of 23 eyes prior to MIRAgel scleral explant removal the common reasons for removal were palpable mass under the eyelid (48%), pain and discomfort (35%), visualization of the buckle eroding through the conjunctiva (26%), diplopia (30%), complete immobility (17%), and signs of infection (17%). 9 …”
Hydrogel buckle intrusion due to progressive swelling is a known complication, which usually requires surgical intervention due to vitreous hemorrhage, retinal detachment, or progressive encroachment into the optic nerve or macula. Hydrogel buckle surgery with successful retinal detachment repair was performed in this one-eyed physician in 1990, and there was slow progressive intrusion towards the macula and optic nerve without surgical intervention for 30 years and with visual acuity maintained at 20/40.
“…A wide range of RR has been reported in the literature 10,[20][21][22][23] after removal of scleral buckles, reaching as high as 34%. Reported rates of intraoperative scleral perforation reach 8% for silicone buckles and range from 0 to 18% for MIRAgel explants.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
