Background: Nd:YAG laser is non-invasive and effective means to deal with the posterior capsule opacification.However safe it may have some inherent complications. Rise of intraocular pressure is frequently encountered and incompletely understood complication of YAG laser capsulotomy and documented with conflicting results.Aims and Objective: To assess the efficacy of Nd: YAG laser capsulotomy in term of visual outcome(Best Corrected Visual Acuity) and also study the changes in IOP after the procedure.Materials and Methods: Study evaluated the changes in IOP and visual acuity after Nd-YAG laser capsulotomy in 100 eyes with significant PCO after uncomplicated cataract surgery with IOL implantation. Complete ocular examination including visual acuity, anterior segment examination with slit lamp, fundus and applanation tonometry were performed pre and post-laser in all cases. Posterior capsulotomy was done with VISULAS YAG III Q-switched Nd: YAG laser machine by ZEISS. IOP was recorded before and then at 1hour, 1 Day, 1 week and 1 month post-laser in order to determine the IOP changes.Results: Pre-laser visual acuity ranged from 1/60 to 6/12. Results showed statistically significant improvement in BCVA with 70% patients had BCVA 6/6, 21% had BCVA 6/9 and 8% having BCVA 6/12 post-laser at 1 month. It was observed that 36% of the patients showed no change in IOP while 64% patients showed elevated IOP. Among these 59% patients show rise in IOP that was ≤5 mm Hg while only 5% of the patients had a rise of more than IOP >5 mm Hg. Most of these patients achieved their baseline IOP within 1 day and only 7 % patient had rise in IOP compared to baseline IOP on day 1. None of the patients show elevated IOP after 1 week.Conclusion: Our study showed that Nd: YAG laser posterior capsulotomy provided excellent results in terms of visual improvement and most of the patients had a rise of <5mm Hg which was transient in nature and routine antiglaucoma medication may not be needed in all the patient undergoing Nd;Yag capsulotomy, however caution should be exercised in glaucomatous, aphakic, high myopic and other high risk patients.Asian Journal of Medical Sciences Vol.8(5) 2017 93-97

Abstract Purpose To evaluate the potential impact of rebubbling on the anterior segment parameters and refractive outcomes in patients with graft detachment following uneventful DMEK for Fuchs endothelial dystrophy (FED). Methods Retrospective institutional cohort study of comparing 34 eyes of 31 patients with rebubbling for graft detachment following Descemet membrane endothelial keratoplasty (DMEK) to 33 eyes of 28 patients with uneventful DMEK. Main outcome parameters were various corneal parameters obtained by Scheimpflug imaging, refractive outcome, corrected distance visual acuity (CDVA), and endothelial cell density (ECD). Results Anterior and posterior corneal astigmatism, corneal densitometry, central corneal thickness, and anterior chamber depth and volume showed no significant differences. Preoperative distribution of astigmatism axis orientations showed a high proportion of anterior corneal with-the-rule astigmatism (71%) in eyes requiring rebubbling. Mean postoperative cylinder in the rebubbling group (1.21 ± 0.85 D) was significantly higher compared to the controls (p = 0.04), while differences in spherical equivalent (SE) were insignificant (p = 0.24). Postoperative CDVA was 0.11 ± 0.11 in the control group compared to 0.21 ± 0.17 in the rebubbling group (p = 0.03). Eyes with subsequent rebubbling demonstrated a significantly higher endothelial cell loss (56% versus 37%) (p < 0.001). Conclusion Apart from higher cylinder values, refractive outcome and corneal parameters assessed by Scheimpflug imaging were comparable in eyes with rebubbling and controls. However, a reduced visual acuity and an increased endothelial cell loss should be taken into consideration prior to rebubbling especially in eyes with circumscribed graft detachment.

Objective To examine the efficacy and safety of yttrium-aluminium garnet (YAG) laser vitreolysis for the treatment of vitreous floaters. Methods Consecutive adult patients with symptomatic vitreous floaters who attended Chongqing General Hospital from April to December 2016 were included in this prospective study. Patients had >3 mm between the vitreous opacity and retina/lens and acceptable quality peri-papillary Optical Coherence Tomography (OCT) images (i.e., signal strength ≥5). Those with history of glaucoma, severe cataracts, vitreous haemorrhages, retinal holes and/or macular disease were excluded from the study. Best corrected visual acuity (BCVA) and non-contact intraocular pressure (IOP) were measured before and for up to 6 months post-YAG laser vitreolysis. Anterior segment photography and peripapillary retinal nerve fibre layer (RNFL) measured by OCT were taken before and 6 months post-procedure. Questionnaires on patient satisfaction were completed 6 months post-procedure. Results No statistically significant differences in BCVA and IOP were observed before or after treatment. Anterior segment photography showed that vitreous opacities partially or completely disappeared after YAG laser treatment. The thickness of RNFL in four directions (upper, below, nasal and temporal) was not statistically significant different before or 6 months after the procedure. 75% patients reported significant improvement and 25% reported moderate improvement. Conclusion The results of this study conducted in a cohort of 30 Chinese patients showed that YAG laser vitreolysis was a well-tolerated and effective treatment for vitreous floaters. Randomised, controlled trials involving large numbers of participants monitored over an extended follow up period are required to confirm these results.
