Abstract Glaucoma is a challenging ocular disease with different but limited treatment approaches. Diode laser through sclera is a traditional way to decrease IOP in advanced glaucomatous eyes, but with micropulse (microsecond pulsing) delivery system it became safer and more effective. In this study we retrospectively summarized IOP changes in eyes that had been treated by micropulse transscleral diode laser cyclophotocoagulation. we focused on glaucomatous eyes that had relatively good visual acuity and we used a new combination of two devices from two different companies which were infrared 810 nm laser source from (LIGHTMED CORPORATION, Tuscan, TAIWAN) with different delivery system the MicroPulse MP3 handpiece probe from (Iridex, Mountain View, CA, USA) in this way we decrease cost and showed a comparable effectivity .

Abstract Purpose To evaluate the efficacy and safety of micro-pulse trans-scleral diode laser cyclophotocoagulation (MP-TSCPC) in Indian eyes with refractory glaucoma. Methods A prospective interventional short-term study was carried out with relatively small sample size of 55 eyes with refractory glaucoma. All eyes had visual acuity (VA) and intraocular pressure (IOP) measurements at baseline, 1 week (1w), 1 month (1 m) and 3 months (3 m). A single surgeon treated all eyes with recommended MP-TSCPC treatment settings. Surgical success was defined as achieving an IOP between 8–21 mmHg or achieving > 20% IOP reduction. Results The age of participants was 56.98 ± 15.74 years. Our study had more number of males. VA (in logMAR) at baseline was 1.38 ± 0.99. VA was 1.43 ± 0.93 at 1w, 1.47 ± 0.94 at 1 m and 1.47 ± 0.96 at 3 m (p > 0.05 for all). IOP (in mmHg) at baseline was 30.38 ± 10.70. IOP was 15.72 ± 6.85 at 1w, 16.98 ± 8.72 at 1 m and 17.60 ± 8.40 at 3 m (p < 0.001 for all). At 3 m, 49 (89.1%) eyes had surgical success. Surgical success was lesser in primary open angle glaucoma (p = 0.03). IOP at baseline showed significant correlation with percentage reduction in IOP at each review (p < 0.05). Use of glaucoma medication reduced from 2.94 ± 0.98 to 2.01 ± 1.16 at 3 m (p < 0.001). At 3 m, hypotony was noted in 4 (7.3%) eyes and reduction in visual acuity was seen in 15 (27.3%) eyes. Conclusion Initial experience in Indian eyes has shown that MP-TSCPC is safe and effective for refractory glaucoma. Patients can expect significant IOP lowering along with reduction in number of topical medications required for control of IOP.

Purpose. To compare the results of intraocular pressure (IOP) reduction by 3 treatment modalities, (a) glaucoma tube implants, (b) noncontact YAG laser cyclophotocoagulation (cycloYAG), and (c) contact transscleral diode laser cyclophotocoagulation (cyclodiode), in cases of advanced glaucoma refractory to alternative treatments.Methods. A consecutive group of 45 eyes that received cycloYAG were matched against two control groups of patients who had received tube surgery or cyclodiode, each control group having been derived from a database of patients.Results. Mean pretreatment IOP improved from 41.3, 38.6, and 32.0 mmHg for the tube, cycloYAG, and cyclodiode groups, respectively, to 16.4, 22.1, and 19.3 mmHg, respectively. Treatment success was achieved in 78%, 69%, and 71% of the tube, cycloYAG, and cyclodiode groups, respectively. Visual acuity deteriorated 2 or more Snellen lines in 16%, 7%, and 9% of the patients in the tube, cycloYAG, and cyclodiode groups, respectively. Complications included retinal detachment, hypotony, and phthisis.Conclusions. All 3 methods provided acceptable IOP lowering in the short and medium term. Control of IOP was best in patients receiving tube surgery. Cyclodiode and cycloYAG treatments were similarly effective in lowering IOP. Tube surgery was associated with a greater incidence of sight threatening complications.

Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

Abstract Background To compare visual performance between the iris-fixated phakic intraocular len (pIOL) and implantable collamer len (ICL) to correct high myopia. Methods Twenty-four eyes underwent iris-fixated pIOL implantation and 24 eyes underwent ICL implantation. At the 6-month follow-up, the best-corrected visual acuity (BCVA) and uncorrected distance visual acuity (UDVA) were compared between the iris-fixated pIOL and ICL groups. The objective scatter index (OSI), modulation transfer function (MTF) cutoff, and ocular aberrations were performed to evaluate postoperative visual quality between the two groups. Results No significant difference was found in UDVA, BCVA, and spherical equivalent between the iris-fixated pIOL and ICL groups (P > 0.05). Six months after surgery, the following values were significantly higher in the ICL group than in the iris-fixated pIOL group: MTF cutoff, strehl ratio and optical quality analysis system values at contrasts of 9 %, 20 %, and 100 % (P < 0.01). The OSI in the iris-fixated pIOL group was higher than in the ICL group 6 months after surgery (P < 0.01). All high-order aberrations were slightly more severe in the iris-fixated pIOL group than in the ICL group 6 months after surgery, although only trefoil (P = 0.023) differed significantly in this regard. Conclusions Both iris-fixated lenses and ICLs can provide good visual acuity. ICLs confer better visual performance in MTF-associated parameters and induce less intraocular light scattering than iris-fixated pIOLs.
