Aim: To study whether succinylated collagen bandage lenses (SCBL) prepared from modified bovine collagen (succinylated collagen) can replace other bandage lenses presently employed to treat various corneal conditions like filamentary keratitis, dry eyes, recurrent corneal erosions, foreign body removal and epithelial trauma. Methods: This observational case study included 32 patients (22 female and 10 male): 8 patients for filamentary keratitis (25%), 10 patients for dry eyes (31%), 4 patients for recurrent corneal erosions (13%), 7 patients for foreign body removal (22%) and 3 patients for epithelial trauma (9%). Their eyes were evaluated for biocompatibility, in vivo transparency, patient comfort, corneal fit, best corrected visual acuity (BCVA), tear fluid level and dissolution rate of SCBL. This was carried out over a 24-hour period of time. Results: SCBL exhibited good transparency and remained transparent throughout the period of study (between 0 and 24 h) in the eyes of patients. SCBL did not cause any irritation, discomfort and foreign body sensation in the eye and eyes remained comfortable throughout the experiment. BCVA in the control group of patients was 1.00 (20/20). Mean (±SD) BCVA before inserting SCBL (in decimal equivalent) was 0.31 (20/60) ± 0.18 (range 0.1– 0.66). BCVA (±SD) changed to 0.25 (20/80) ± 0.18 4 h after the application of SCBL and 0.27 (20/70) ± 0.18 24 h after the application of SCBL, with a safety index of 1.20. The mean (±SD) tear fluid level before application of SCBL was 11.9 ± 5.39 h (range 3–24 mm) and changed to 13.9 ± 5.68 h (range 5–28 mm) after 4 h of application of SCBL and 15.9 ± 5.72 h (range 7–30 mm) after 24 h with a safety index of 13 mm. The mean (±SD) dissolution rate of SCBL in the control group of patients was 17.8 ± 8.65 h (range 10–24 h) and the mean (±SD) dissolution rate in the experimental group was 22.2 ± 9.29 h (range 10–24 h). We report the use of SCBL in various corneal conditions. Conclusion: The present study showed that SCBL has complete corneal fit and good comfort in human eyes. Transparency was maintained for a longer period along with fair visual acuity and improvement in tear fluid levels. The disadvantages of other bandage lenses presently used to treat various corneal conditions could be overcome by the use of SCBL lenses.
