BARCELONA, Spain -- Deep sclerectomy with a hyaluronic acid implant offers good intraocular pressure control with few complications in patients with pseudophakia and open-angle glaucoma, according to Rafal Leszcynski, MD.
Dr. Leszcynski presented here at the International Glaucoma Symposium. Thirty eyes of 30 patients with posterior chamber IOLs and uncontrolled open angle glaucoma underwent deep sclerectomy with the SK-Gel implant (Corneal Laboratoire). There were 17 males and 13 females, ages ranging from 45 to 66 years old. Each patient received the SK-Gel implant 5 to 11 years after undergoing extracapsular cataract extraction and posterior chamber IOL implantation. Non-penetrating deep sclerectomy with the SK-Gel implant was performed with use of antibiotics and steroids. Patients were followed for 12 months.
Mean preoperative IOP was 26.3 mm Hg and was reduced to a mean IOP of 7.2 mm Hg at 1 day postoperatively. At 1 month, mean IOP was 16.7 mm Hg, and at 12 months, mean IOP was 17.7 mm Hg. Complete success rate, defined as IOP below 21 mm Hg without medical treatment, was 60% at 1-year follow up.
According to Dr. Leszcynski, visual acuity diminished in three eyes due to opacification of the posterior capsule. Twelve eyes needed additional procedures such as goniopuncture, needling, use of 5-fluorouracil and betaxol.
The most serious adverse complication was fibrosis of the filtering bleb, Dr. Leszcynski said.
