To compare the intraocular pressure (IOP) requirement of ocular hypotensive treatment and visual recovery after surgery at 1,3,6 and 12 months after surgery in eyes with primary open angle glaucoma (POAG) or pseudoexfoliative glaucoma (PXG) treated by Phaco-Express.
The records of all patients with POAG and PSX who had undergone combined cataract and Ex-press shunt device surgery in our centre between 2013 and 2015 were considered for inclusion. Inclusion criteria were Phaco-Express surgery and one-year follow-up period after surgery. Eyes with intraoperative complications were excluded. IOP and number of topical drugs were studied.
Sixteen eyes operated by Phaco-Express were included, 9 diagnosed with POAG and 7 with PXG. There were no statistically significant differences in age, IOP, number of pre-surgery treatments and visual acuity between both groups. Mean pre-surgical IOP in POAG group was 18.0± 6.5 mmHg and decreased by 11% at first month, 18% at third month, 22% at sixth months and 26% at one year after surgery (p<0.05 except for one month). Number of drugs needed before surgery was 3.4 ± 0.7 decreased to 0.4 ± 0.8, 0.8±1.1, 1.3±0.7 and 1.1±0.7 at one, three, six and twelve months after surgery.
Mean IOP in PXG group decreased from 19.5 ± 6.1 mmHg by 30%, 39%, 33% and 35% at one, three, six and twelve months post-surgery respectively (p<0.05 at six and twelve months)(Fig 1). Number of drugs decreased from 2.71 pre-surgery to 0.17 ± 0.48, 0.00, 0.33 ± 0.81 and 1.00 ±1.54 at 1, 3, 6 and 12 months respectively (Fig 2).
No statistically significant difference between groups was observed except for the number of hypotensive drops needed at 6 months after surgery: 1.3 in POAG vs 0.3 in PXG (p<0.05).
Combined Phaco-Express surgery is an excellent alternative for IOP control and achieves a reduction in hypotensive topical treatments a yearafter the intervention in POAG and PXG eyes
