Purpose: To research the advantage of using calcium plaque scissors in conjunctival flap surgery for calcified scleromalacia after cosmetic conjunctivectomy.
Methods: We analyzed 55 eyes that had undergone conjunctival flap surgery for calcified scleromalacia occurring after cosmetic conjunctivectomy. Surgical blade was used in 30 eyes (Group 1) and calcium plaque scissors in 25 eyes (Group 2). Time after conjunctivectomy, plaque size, operation time and visual acuity before and after the flap surgery were analyzed and compared. Additionally, necessity of additional scleral surgery was evaluated. Optical coherence tomography (OCT) of the sclera was performed both pre- and postoperatively and the results were compared.
Results: An average of 3.9 ± 1.0 years elapsed until conjunctival flap surgery and follow-up time was 5.2 ± 3.8 months. Post conjunctivectomy time and plaque size were similar in both groups (p = 0.87 and 0.49, respectively). The surgery time in Group 2 was shorter than in Group 1 (17.5 ± 6.3 minutes and 21.9 ± 8.5 minutes, respectively, p = 0.20). Uncorrected visual acuity was similar in both groups before and after conjunctival flap surgery (p = 0.53 and p = 0.20, respectively). In Group 1, one sclera transplantation and three Ologena™ insertion surgeries were performed as an additional scleral surgery. Based on OCT, calcium plaque scissors were confirmed as a new surgical tool for calcium plaque removal with minimal scleral damage.
Conclusions: Using calcium plaque scissors when performing conjunctival flap surgery for calcium plaque removal that occurred after cosmetic conjunctivectomy reduces the necessity of an additional scleral surgery and surgery time.
