The introduction of optical coherence tomography has allowed accurate measurement of the size of macular holes. A retrospective consecutive review was performed of 21 patients undergoing macular hole repair with vitrectomy, gas tamponade, and autologous platelet injection and we assessed the effect of macular hole parameters on anatomic and functional outcomes. We looked at the demographic features, final visual outcome, and anatomical closure. Twenty-one patients were included in the study. They underwent routine vitrectomy with gas tamponade (C₃F₈) and injection of autologous platelets. All patients were advised to maintain a facedown posture for 2 weeks. Anatomical closure was confirmed in all cases and 20 out of 21 of patients had improved postoperative visual acuity by two or more lines. In our series, the macular hole dimensions did not have much effect on the final results. The use of autologous platelets and strict facedown posture seems to be the deciding factor in good anatomical and visual outcome irrespective of macular hole dimensions.

Purpose: To report the surgical outcome in seven cases of optic disc pit associated maculopathy. Methods: This was a retrospective case-note analysis of presenting features, pre- and postoperative visual acuities, surgical procedures, complications, and follow-up. The principal treatment in all the cases was pars plana vitrectomy, posterior hyaloid peel, endolaser to the papillomacular bundle temporal to the disc, and internal tamponade with gas or silicone oil. Results: Of the four male and three female patients, two were children. All the patients had posterior hyaloid peeling during the vitrectomy and endolaser. Six patients had intraocular gas tamponade and one had silicone oil. Four patients needed a second surgical procedure to obtain a satisfactory anatomic and visual outcome. Postoperatively, four patients had an improvement of 2 or more Snellen lines. One patient with a history of multiple surgeries developed high intraocular pressure postoperatively and cataract. The mean follow-up period was 9.1 months. Conclusions: Serous retinopathy associated with optic disc pit responds well to early vitrectomy, endolaser, and internal tamponade. Silicone oil was effective in one refractory case. Cumulative data are required to define the management of this condition.

Purpose: To compare the postoperative visual acuity curves following 3 pseudophakic presbyopic correction techniques. Setting: Department of Ophthalmology, University Hospital of Alexandroupolis, Alexandroupolis, Greece. Design: Prospective, randomized, comparative trial. Methods: For this study, patients with stage 2 Lens Opacities Classification System III cataract were divided into 3 study groups: (1) premium monovision group, including patients who received the Panoptix intraocular lens (IOL) in the recessive eye and Vivity IOL in the dominant one; (2) bilateral trifocal group, including those who received bilaterally the Panoptix IOL; and (3) bilateral xEDOF group, including patients who received bilaterally the Vivity IOL. Postoperative bilateral uncorrected distance visual acuity was measured at 25.5, 28, 33, 40, 50, 66, 100, 200, and 300 cm distances. Spline curve fitting was attempted, and areas of the curves (AOCs) and curvature k were calculated. All patients responded to the National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25). Results: 90 patients were equally divided into the 3 groups. Premium monovision and bilateral trifocal implantations delivered similar visual acuity (all AOC P > .05); however, the trifocal patients suffered from drops in vision acuity in certain distance ranges as expressed by negative curvature values. Bilateral xEDOF patients demonstrated worse near vision acuity (P < .05). Premium monovision patients reported better scores in NEI-VFQ 25 (P = .03) and in the near activities (P = .02) and distant activities (P = .04) subscales. Conclusions: All surgical options provided impressive outcomes. Premium monovision appeared to deliver the best results.

Purpose: To evaluate the effects of 2 different amounts of commonly used intravitreal agents on anterior segment morphology in conjunction with intraocular pressure (IOP) changes. Methods: Two groups of 46 patients who received intravitreal injection of bevacizumab (group 1, 0.05 mL) or bevacizumab–triamcinolone acetate (TA) combination (group 2, 0.1 mL) were included in this prospective study. All patients underwent anterior segment optical coherence tomography (AS-OCT) imaging with Visante OCT and IOP measurement before and at 5 minutes, 1 hour, and 3 hours after injection. Anterior chamber depth (ACD), angle-opening distance (AOD 500-750), trabecular–iris space area (TISA 500-750), and anterior chamber angle (ACA) were measured. Results were compared between groups and measurement time points. Results: The mean change in IOP showed significant difference between baseline and first measurements after the injection in group 1 and group 2 (p = 0.012, p = 0.008, respectively). There was a statistically significant difference from baseline in ACD at the first and second measurements in group 2 (p = 0.005, p = 0.018, respectively). All angle parameters showed insignificant decrease from baseline at all measurement time points in both groups (p>0.05 for each). The difference of angle parameters after injection was not statistically significant between the groups (p>0.05 for each). Conclusions: Intravitreal injection of bevacizumab (0.05 mL) or bevacizumab-TA combination (0.1 mL) caused a change in anterior segment configuration determined by AS-OCT. The changes in anterior chamber parameters returned to baseline values with the normalization of IOP values after the first few minutes of injection.

Purpose: Contemporary monovision techniques use premium intraocular lenses (IOLs), either in both eyes or at least in the non-dominant one. Primary objective of this study was to compare the efficacy of premium monovision (implantation of the trifocal diffractive Panoptix IOL in the non-dominant eye and the bifocal hybrid refractive-diffractive Restor IOL in the dominant eye), against bilateral myopic monovision (implantation of the monofocal SN60WF IOL targeting − 0.50 D in the dominant eye and − 1.25 D myopia in the non-dominant one), hybrid monovision (implantation of Panoptix in the non-dominant eye and SN60WF in the dominant eye) and bilateral trifocal implantation (with bilateral Panoptix implantation). Methods: This is a prospective, comparative, clinic-based trial. Cataract patients populated four study groups: Monovision Group (MoG), Multifocal Lens Group (MfG), Hybrid Monovision Group (HmG) and Premium Monovision Group (PmG). Binocular Uncorrected Distance Visual Acuity (UDVA), Uncorrected Reading Acuity and Critical Print Size at 60cm (UIRA, UICPS) and at 40cm (UNRA, UNCPS), contrast sensitivity, vision-related functional impairment, dysphotopsia symptoms and spectacle dependence were evaluated 6 months following the operation of the second eye. A mathematical model was constructed, which calculated the relative efficacy of each surgical intervention. Results: A total of 120 participants were recruited and populated equally the study groups. Significant improvement of preoperative UDVA was observed in all study groups. No significant differences could be detected in postoperative UDVA and UIRA (p = 0.24) among study groups, while significant differences were noticed in UICPS (p = 0.04), UNRA (p = 0.02) and UNCPS (p = 0.01). Dysphotopic phenomena (glare and shadows) were significantly more in the MfG arm followed by the PmG group (p = 0.04 and p = 0.02, respectively), while perceived difficulty and spectacle independence rates were significantly better in PmG group. PmG presented the best overall relative efficacy. Conclusion: All surgical techniques present satisfactory outcomes. Premium monovision seems to demonstrate the best outcomes.

A systematic review of the recent literature regarding the current image-guided systems used for cataract surgery or refractive lens exchange was performed based on the PubMed and Google Scholar databases in March 2018. Literature review returned 21 eligible studies. These studies compared image-guided systems with other keratometric devices regarding their accuracy, repeatability and reproducibility in measurement of keratometric values, astigmatism magnitude and axis, as well as in IOL power calculation. Additionally, the image-guided systems were compared with conventional manual ink-marking techniques for the alignment of toric IOLs. In conclusion, image-guided systems seem to be an accurate and reliable technology with measurements of high repeatability and reproducibility regarding the keratometry and IOL power calculation, but not yet interchangeable with the current established and validated keratometric devices. However, they are superior over the conventional manual ink marking techniques for toric IOL alignment.
