Abstract Details

Purpose:

Comparative outcomes of CO2 Laser-Assisted Sclerectomy Surgery (CLASS) and Trabeculectomy in patients with open-angle glaucoma (OAG) both combined with phacoemulsification.

Setting:

Research Department, Oftalmosalud Eye Institute, Lima-Peru, Av. Javier Prado Este 1142, San Isidro, Lima, Peru

Methods:

A retrospective analytical study included 84 eyes. We compared the results of both surgical procedures, Phaco亶鯸臩� implant performed between 2013-2014 and Phacoࢰቋꈇ� implant performed between 2015-2016. Patients diagnosed with OAG were included. IOP was measured preoperatively, at 1, 3, 6 and 9 months and 1 year. Corrected visual acuity (BCVA) was measured preoperatively, at 1 and 9 months and 1 year. Lastly, medication use was measured preoperatively, at 9 months and 1 year. Complete success was defined as IOP<18mmHg without medication and qualified success as IOP<18mmHg with or without medication one year post-operatively.

Results:

47 eyes included in the Trabeculectomy group and 37 eyes in the CLASS group. Both groups had a follow-up of 1 year. In the Trabeculectomy group, the mean�Â�±SD IOP preoperative compare to the 1 year follow-up were 19.11 �Â�± 9.30 with decrease to 11.91�Â�±1.66 with a 37,6% of IOP reduction, BCVA from 0.26�Â�±0.45 to 0.39 �Â�± 0.61 and medications from 3.02 �Â�± 1.07 to 1.47 �Â�± 1.08. Complete success rate was 30.8% and qualified success of 100%. In the CLASS group mean�Â�±SD IOP preoperative compared to 1 year follow up were 22.73�Â�±9.21 with reduction to 12.46�Â�±2, with a 47,2% of IOP reduction, BCVA from 0.26�Â�±0.31 to 0.10�Â�±0.18 and medications from 3.51�Â�±0.76 to 0.51�Â�±0.65. Complete success rate was 53.8% and qualified success of 97.2%.

Conclusions:

Our study demonstrated that CO2 Laser-Assisted Sclerectomy Surgery (CLASS) is a safe technique that allows better reduction of IOP and medications as well as maintaining better visual acuity with lower rates of postoperative complications than conventional Trabeculectomy.
