Summary
The double scleral closure technique for evisceration surgery results in fewer implant complications. This method allows for larger implants and is associated with lower rates of implant exposure and extrusion compared to single scleral closure.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Ocular Implants
Background:
- Evisceration with implant insertion is a common procedure for managing various ocular conditions.
- Implant exposure and extrusion are known complications following evisceration.
- Optimizing surgical techniques is crucial for improving outcomes and patient satisfaction.
Purpose of the Study:
- To compare the incidence of implant exposure and extrusion between single and double scleral closure techniques after evisceration.
- To evaluate the impact of different scleral closure methods on implant outcomes.
Main Methods:
- Retrospective cohort study of 81 patients undergoing evisceration with primary implant insertion over 18 years.
- Patients were divided into single (n=42) and double (n=39) scleral closure groups.
- Clinical data and operation records were reviewed for implant complications and characteristics.
Main Results:
- The double scleral closure group received larger implants (19.7 mm vs. 17.9 mm).
- Implant exposure rates were significantly higher in the single scleral closure group (26% vs. 3%).
- Implant extrusion rates were also significantly higher in the single scleral closure group (26% vs. 0%).
Conclusions:
- The double scleral closure technique enables the use of larger implants.
- This technique is associated with significantly lower rates of implant exposure and extrusion.
- Double scleral closure is recommended as a superior technique for primary implant placement during evisceration.
