This Technique Combined with Cataract Surgery Appears Beneficial
Combining goniotomy–using the Kahook Dual Blade–with cataract surgery appears to consistently lower intraocular pressure (IOP), according to a study involving 105 eyes, as reported by Linda L. Burk, MD, an ophthalmology specialist at Dallas Eye and Ear in Dallas, TX, during the American Society of Cataract and Refractive Surgery’s 2018 annual meeting in Washington, DC.
Participants with varying levels of glaucoma severity who had previous trabeculectomy, glaucoma implant, laser peripheral iridectomy, or selective laser trabeculoplasty were included. 80% were black, 60% had diabetes, and half were taking a blood thinner. 30% had prior glaucoma laser or incision surgery. All underwent the combined procedure. Investigators measured IOP early postoperatively and at 3-month intervals for a year. Among the results:
- Preoperatively, average IOP was 19.9 mmHg, and participants were on an average of nearly 2 medications.
- IOP dropped to an average 16.0 mmHg at 1 month, and remained there throughout the first year.
- 9 in every 10 eyes required no meds after the procedure.
- No choroidal detachment, hypotony, or flat chambers were seen.
- 2 eyes required washouts, 1 combined with an Ahmed.
