Aim This study aims to compare the efficacy and safety of femtosecond (FS) laser capsulotomy between mature and non‐mature cataracts. Setting Kaskaloglu Eye Hospital, single center study. Design Prospective, controlled, and masked cross‐sectional disease. Methods A total of 133 eyes of 97 patients were included in this study. The Lens Opacities Classification System III grading scale was used in order to classify cataracts into two groups: mature and non‐mature. The LenSx laser system (Alcon Labs Inc, Fort Worth, TX) was used. Data were extracted from patient charts, which included cataract grading, capsulotomy problems (tag, incomplete capsulotomy, and anterior capsule tears). Results The mean age was 69.2 ± 10 years (64 males, 34 females). There were 50 eyes in Group I and 83 eyes in Group II. In 20 out of 133 eyes (15%) capsule tags occurred. Of these 20 eyes, 12 were in Group I, and 8 were in Group II. The number of tag occurrences was statistically higher in Group I when compared to Group II ( P = 0.011). Incomplete capsulotomy was significantly higher in Group I when compared to Group II ( P < 0.0001). Free capsulotomy was present in 36 out of 50 eyes (72%) in Group I and 75 out of 83 eyes (90%) in Group II ( P = 0.03). Conclusion The grade of cataract significantly increased the number of suboptimal capsulotomy outcomes in FS laser capsulotomy. In mature cataract cases, the surgeon should be aware of limitations of FS laser in order to prevent capsule‐related complications. Further studies of the relationship between pulse energy, patient interface design, and capsule burst strength will help elucidate the optimum parameters for laser capsulotomy creation in mature cataracts.
