Intraocular Pressure 1 Year After Phaco-Canaloplasty
Narrative Responses:
Purpose
To demonstrate that at one year Phaco-canaloplasty is a safe and efficacious procedure in terms of IOP reduction and visual improvement in Primary open-angle glaucoma patients with cataracts.
Methods
In a descriptive, non randomised prospective trial over a period of 6 months 38 eyes of 50 patients with primary open-angle glaucoma were selected for phaco canaloplasty and operated based on the following criteria. Visually significant cataracts with IOP over 25 mmHg on maximally tolerated medication or intolerance to or non compliance with glaucoma medication with IOP over 25mmHG. Phaco Canaloplasty with foldable IOL implantation was carried out with a fibreoptic canaloplasty device. IOP was measured with applanation tonometry at day 2, day 30, day 180, one year. Vision was recorded on day 7, day 30, and 1 year.
Results
Day 2 IOP was between 2-7. On day 30, 9-14. Day 180, 12-15. Between 1- 6 months 12 eyes were deemed to be “failures”(IOP over 20 mmHg). These cases were “revised” internally by trabecular membrane rupture. By 1 year 9 eyes of 6 patients were lost to follow-up. 35 eyes had pressures between 12 and 17 without any meds. Vision was 6/6-6/9 in 27of 38 eyes at 7 days. By day 30, 36 out of 38 eyes were between 6/9 - 6/6. By one year it was 25 eyes between 6/9 and 6/6 as some eyes were lost to follow-up.
Conclusion
Phaco- Canaloplasty is efficacious and safe in glaucoma patients with cataracts by decreasing IOP and increasing vision.
