Abstract Details


To evaluate the efficacy and safety of intracameral perfluoroethane (C3F8) gas along with compression sutures versus c3f8 gas alone for the treatment of acute hydrops secondary to keratoconus.


Bharti eye hospital, New Delhi, India


Retrospective, interventional case series. 20 eyes of 20 patients who presented with acute hydrops secondary to keratoconus between July 2015 and June 2016 were consecutively recruited. Patients were divided into 2 groups. Group 1 case was treated with 14% iso expansile concentration of C3F8 gas along with compression sutures. Group 2 cases were treated with intracameral C3F8 gas alone. with intracameral. All the patients, followed up for 6 months.Preoperative and postoperative best-corrected visual acuities (BCVA), intraoperative and postoperative complications, and time taken for resolution of corneal edema were assessed.


The mean age of the cohort was 24.1±5.5 years. All the patients required only one injection during the treatment period. The C2F6 gas persisted in the anterior chamber between 6 and 10 days. Mean BCVA at presentation was 6/60 or less in all patients. Improvement of BCVA was achieved postoperatively in all cases (100%) patients. There was a statistically significant difference between the visual outcomes in two groups. The average time between initial presentation and complete resolution of corneal edema was 14+/-7 days in group 1 and 62.0±30 days in-group 2. No intra-operative or postoperative complication noted.


compression sutures with intracameral isoexpansile concentration of C3F8 gas serves as a safe and effective treatment modality for patients with acute hydrops. Combined procedures is better then conventional intracameral gas injection.
