Aim: To investigate the effects of a new opening pattern in neodymium:yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy on visual function.
Methods: This technique was conducted along a circular pattern. The energy ranged between 0.8 and 1.2 mJ/pulse was consumed and mean total energy levels were 74±21 mJ (mean±standard deviation: SD, from 40 to 167) and laser shots aimed at 150 µm away behind a datum point and went along an imaginary line which extends 0.5 mm inside from optic margin and into the circular en bloc pattern. Vitreous stands were attached with fragment and then they were cut off by the laser after circular application. The circular fragment was completely separated from vitreous, and then this fragment was quickly sunk in intravitreal space.
Results: The follow-up period ranges from at least a week to 40mo, making 15.8mo on average. The procedural outcome showed 96% (74 eyes out of the 77 eyes) enhancement in patients' visual acuity. Cystoid macular edema or retinal detachment was not observed in any of the patients during follow-up periods.
Conclusion: This new technique is expected to improve the weaknesses that the conventional procedures have by adding the process to cut off vitreous stands attached with the fragment by the laser to the circular application.

Purpose: Frequency doubling of neodymium-doped yttrium aluminum garnet (Nd-YAG) laser results in emission of photocoagulating 532 nm light compared with photolytic 1064 nm emission. The ergonomic benefits of solid-state lasers led to replacement of older coagulating lasers in ophthalmic centres by frequency-doubled Nd-YAG laser. Our study aims to evaluate safety and efficacy of frequency-doubled Nd-YAG laser for photocoagulation of corneal neovascularisation (NLPC).

The purpose of this study is to investigate the impact of Nd-YAG laser capsulotomy on retinal and choroidal structures. Thirty-four eyes from 32 patients with PCO were included.

Background: Ecchymoses occur due to various insults to the skin which generally heals spontaneously within 2-3 weeks, with restoration of normal skin color. However, the prominent skin discolouration is troublesome for patients, prompting them to seek remedies for quick resolution. We highlight the importance of using long pulsed NdYAG laser as a treatment modality to speed the resolution of ecchymoses from 14 days to 24-48 hr in skin-type V-VI with negligible side effects, as its potential use is not widely known.

Objective: The aim of this clinical trial was to evaluate the effectiveness of Piano level laser therapy using Nd-YAG laser and intramuscular EGF injection in pain alleviation, function, and quality of life improvement in patients suffering from myogenic TMD.
Materials And Methods: A randomized clinical trial was performed on 29 patients suffering from chronic painful myogenic TMD based on diagnostic criteria for temporomandibular disorders. Group I (n = 13patients) was treated using 1064 nm Nd-YAG Laser (4 sessions once/week).
