In this study 37 eyes were randomized to receive PCP and 38 eyes to receive phaco-DS [ 70 ]. Quality of life (QoL) was evaluated by the means of the National Eye Institute Visual Function Questionnaire-25 items (NEI-VFQ-25).…”

Canaloplasty in the Treatment of Open-Angle Glaucoma: A Review of Patient Selection and Outcomes

Canaloplasty is a relatively new non-penetrating surgery for the reduction of intraocular pressure in patients affected by glaucoma. The technique uses a microcatheter to perform a 360 º cannulation of Schlemm’s canal and leaves in place a tension suture providing an inward distension. It aims to restore the physiological outflow pathways of the aqueous humour and is independent of external wound healing. Several studies have shown that canaloplasty is effective in reducing intraocular pressure and has a low rate of complications, especially compared with trabeculectomy, the gold standard for glaucoma surgery. Currently, canaloplasty is indicated in patients with open-angle glaucoma, having a mild to moderate disease, and the combination with cataract phacoemulsification may provide further intraocular pressure reduction. This article reviews canaloplasty indications, results and complications and analyses its outcomes compared with traditional penetrating and non-penetrating techniques.

This study aimed to assess refractive astigmatism, in phaco-canaloplasty (PC) vs phaco-non-penetrating deep sclerectomy (PDS) in a randomized, prospective study within 24 months. Patients were randomized pre-operatively, 37 underwent PC and 38 PDS. The following data was collected: BCVA, IOP, number of antiglaucoma medications, refraction with autokeratorefractometry. The assessment of astigmatism was simple arithmetic and vector analysis (calculations included cylinder with axis in form of centroids) and included double angle plots and cumulative refractive astigmatism graphs. Pre-operative mean BCVA in PC was 0.40 ± 0.43 and was comparable to BCVA in PDS 0.30 ± 0.32logMAR (P = 0.314). In the sixth month follow-up, mean BCVA showed no difference (P = 0.708) and was 0.07 ± 0.13 and 0.05 ± 0.11, respectively. However, 2 years after the intervention mean BCVA was better in PC 0.05 ± 0.12 than in PDS 0.12 ± 0.23 and it was statistically significant (P = 0.039). Mean astigmatism in PC at baseline was 1.13 ± 0.73Dcyl, at 6 months it was 1.09 ± 0.61 and at 2 years 1.17 ± 0.51. In PDS at baseline 1.35 ± 0.91 at 6 months 1.24 ± 0.86 and at 2 years 1.24 ± 0.82. There were no differences between the groups in mean astigmatism throughout the study. Centroids (mean of a cylinder with axis) in PC were pre-operatively 0.79D@172˚ ± 1.10Dcyl, at 6 months 0.75D@166˚ ± 1.01 and at 24-months 0.64D@164˚ ± 1.11 and in PDS pre-operatively 0.28D@10˚ ± 1.63D at 6 months 0.26D@11˚ ± 1.5 and at 24-months 0.47D@20˚ ± 1.43. The direction of mean astigmatism was against the rule in all analyzed time points. The mean baseline IOP in PC was 19.4 ± 5.8 mmHg and 19.7 ± 5.4 mmHg in PDS(P = 0.639). From the 6-month IOP was lower in PC, at 24-months it was 13.8 ± 3.3 mmHg in PC and 15.1 ± 2.9 mmHg in PDS(P = 0.048). In both groups preoperatively patients used median(Me) of three antiglaucoma medications(P = 0.197), at 24-months in PC mean 0.5 ± 0.9 Me = 0.0 and 1.1 ± 1.2 Me = 1.0 in PDS(P = 0.058). Both surgeries in mid-term observation are safe and effective. They do not generate vision-threatening astigmatism and do not even change the preoperative direction of mean astigmatism. Refractive astigmatism is stable throughout the observation.

PurposeThis study aimed to assess refractive astigmatism, in Phaco-Canaloplasty (PC) vs Phaco-Non-Penetrating Deep sclerectomy (PDS) in a randomized, prospective study within 24 months.MethodsPatients were randomized pre-operatively, 37 underwent PC and 38 PDS. The following data was collected: BCVA, IOP, number of antiglaucoma medications, refraction with autokeratorefractometry. The assessment of astigmatism was simple arithmetic and vector analysis included double angle plots and cumulative refractive astigmatism graphs.ResultsPre-operative mean BCVA in PC was 0.40±0.43 and was comparable to BCVA in PDS 0.30±0.32logMAR (P=0.314). In the sixth month follow-up, mean BCVA showed no difference (P=0.708) and was 0.07±0.13 and 0.05±0.11, respectively. However, two years after the intervention mean BCVA was better in PC 0.05±0.12 than in PDS 0.12±0.23 and it was statistically significant (P=0.039). Mean astigmatism in PC at baseline was 1.13±0.73Dcyl and 1.35±0.91 for PDS(P=0.544). At six months it was 1.09±0.61 and 1.24±0.86 respectively,(P=0.595). At two years 1.17±0.51 for PC and 1.24±0.82(P=0.917). The direction of mean astigmatism was against the rule throughout observation for both groups. Centroids pre-operatively were 0.79D@172˚±1.10Dcyl in PC and 0.28D@10˚±1.63D in PDS. At six months 0.75D@166˚±1.01 and 0.26D@11˚±1.5, respectively. At 24-months 0.64D@164˚±1.11 and 0.47D@20˚±1.43. The mean baseline IOP in PC was 19.4±5.8mmHg and 19.7±5.4mmHg in PDS(P=0.639). From the six-month IOP was lower in PC, at 24-months it was 13.8±3.3mmHg in PC and 15.1±2.9mmHg in PDS(P=0.048). In both groups preoperatively patients used median(Me) of 3 antiglaucoma medications(P=0.197), at 24-months in PC mean 0.5±0.9 Me=0.0 and 1.1±1.2 Me=1.0 in PDS(P=0.058). ConclusionsBoth surgeries in mid-term observation are safe and effective. They do not generate vision-threatening astigmatism and don’t even change the preoperative direction of mean astigmatism. Refractive astigmatism is stable throughout the observation.
