Exposure of intrascleral implants

Area of Science:

• Ophthalmology
• Retinal Surgery
• Ocular Implants

Background:

• Scleral buckling is a common procedure for retinal detachment.
• Intrascleral implants are used in some scleral buckling techniques.
• Implant exposure is a potential complication.

Purpose of the Study:

• To identify the incidence and risk factors for intrascleral implant exposure after scleral buckling.
• To describe the management and outcomes of exposed intrascleral implants.

Main Methods:

• Retrospective chart review of 709 patients undergoing scleral buckling.
• Analysis of factors associated with intrascleral implant exposure.
• Documentation of time to diagnosis, surgical removal, and complications.

Main Results:

• 17 patients (2.4%) experienced intrascleral implant exposure.
• Risk factors included temporal/anterior implant location, large implant size, thin sclera/dehiscence, multiple surgeries, and contamination.
• Average time from diagnosis to removal was 2.1 months.
• 16 of 17 exposed implants required removal; one case had retinal detachment with massive vitreous retraction.

Conclusions:

• Intrascleral implant exposure is an uncommon but significant complication of scleral buckling.
• Specific surgical and patient factors increase the risk of exposure.
• Prompt diagnosis and removal are generally successful, with minimal complications.
