Postoperative Pain after Different Transscleral Laser Cyclophotocoagulation Procedures.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Management

Background:

• Glaucoma treatment options are expanding, necessitating clear evidence on surgical differences.
• Choosing the optimal surgical approach requires understanding distinct features of each procedure.

Purpose of the Study:

• To compare postoperative pain intensity between continuous wave transscleral cyclophotocoagulation (CW-TSCPC) and micropulse transscleral cyclophotocoagulation (MP-TSCPC).
• To identify factors influencing postoperative pain following these glaucoma surgeries.

Main Methods:

• Retrospective analysis of 243 glaucoma patients undergoing CW-TSCPC or MP-TSCPC.
• Pain intensity assessed using a numeric rating scale (NRS) during hospitalization.
• Data analyzed using univariable and multivariable models.

Main Results:

• No significant difference in postoperative pain was found between CW-TSCPC and MP-TSCPC in the multivariable model.
• Univariable analysis initially suggested lower pain with MP-TSCPC, but this was not sustained.
• Simultaneous anterior retinal cryotherapy was strongly associated with increased postoperative pain (OR 4.41).

Conclusions:

• The choice between CW-TSCPC and MP-TSCPC did not significantly impact postoperative pain in the multivariable analysis.
• Anterior retinal cryotherapy is a significant risk factor for increased postoperative pain in glaucoma surgery.
• Further research may refine patient selection for different transscleral cyclophotocoagulation modalities.
