The first experience of using femtosecond laser in the treatment of anterior capsular contraction syndrome

Prevention and treatment of anterior capsular contraction syndrome (ACCS) is a relevant problem in cataract surgery. Purpose. The study was performed to develop a femtosecond laser-assisted technique for anterior capsulotomy in anterior capsular contraction syndrome and assess its preliminary results in preventing the progression of pathological changes in the capsular bag. Material and methods. The examination and femtosecond laser-assisted treatment without additional surgical intervention was performed in 6 patients (6 eyes) aged 69 to 73 years with anterior capsular contraction syndrome. Femtosecond laser-assisted anterior capsulotomy was performed using the VICTUS system (Technolas Perfect Vision, Germany). Capsulotomy diameter was 4.0—4.5 mm, laser radiation energy — 9000 nJ, laser exposure depth 900—1000 μm. Results. The diameter of the anterior capsulotomy before treatment was 2.85 mm [2.75; 2.93]. After 1 month, the diameter of the anterior capsular opening was 2.88 mm [2.78; 2.96] (p>0.05). One year after femtosecond laser intervention, the anterior capsulotomy opening was almost the same shape and diameter — 2.84 mm [2.74; 2.94] (p>0.05). Conclusion. Femtosecond laser-assisted circular capsulotomy is an effective and safe method for preventing the progression of anterior capsular contraction syndrome in the absence of severe IOL decentration and for maintaining the diameter of the anterior capsular opening of at least 2.5—3.0 mm.
