Purpose To evaluate and compare the changes in refraction and effective intraocular lens (IOL) position between a plate-haptic IOL and a c-loop single-piece IOL after neodymium-doped yttrium aluminium garnet (YAG) laser posterior capsulotomy. Methods In a prospective study, anterior chamber depth and subjective refraction were measured in 110 pseudophakic eyes from 110 patients, before and 1 ...

BACKGROUND AND OBJECTIVE We investigated the yttrium aluminum garnet (YAG) capsulotomy rates in various intraocular lenses (IOLs). STUDY DESIGN/PATIENTS AND METHODS We retrospectively analyzed 23,440 eyes implanted with either MA60BM, MA60AC, VA-60BB, CeeOnEdge, Clariflex, Technis Z9002, SI-40NB, or UV26T IOLs. We calculated the YAG capsulotomy rates at 1, 3, 5, and 10 years post lens implant...

A Prospective hospital based study to note the efficacy of Nd Yag Peripheral Iridotomy (PI) in the treatment of acute primary angle closure glaucoma was carried out in Nepal Eye Hospital from Jan 2007 to Jan 2008. All the Patients (n=50) with acute primary angle closure glaucoma admitted to our hospital were selected for the study. Patients with secondary angle closure glaucoma were excluded. I...

We retrospectively reviewed the charts of 40 patients who underwent an uneventful phacoemulsification in both eyes and had an Acrylic IOL (AcrySof) implanted in one eye and a Silicone IOL (SI 30/S 140) in the other. A subset of 18 patients had a mean follow up of 1 1/2 year. In the Acrylic group 1 patient (5.5%) underwent a posterior Yag-capsulotomy. In the Silicone group 6 patients (30%) under...

Herein we report a clinical case of premacular hemorrhage treated with neodymium-doped yttrium aluminum garnet (Nd: YAG laser puncture). A 34-year-old Chinese female was administrated to the clinics with complaints of sudden vision loss of left eye (LE) several days before. The best-corrected visual acuity (BCVA) was reduced to light perception. Fundoscopy showed a large and dense premacular he...

CASE REPORT We present the case of a 48 year-old man who had a sudden onset of vomiting, headache and loss of consciousness. The visual acuity was severely reduced in the left eye, with a large subhyaloid haemorrhage being observed in the fundus. DISCUSSION The combination of subarachnoid haemorrhage and a vitreous haemorrhage is called Terson syndrome. The details of the treatment of this ca...

Lichen mosaics on different-textured schists located in the Coa Valley (Portugal) and Siega Verde (Spain) archaeological sites were cleaned using different chemicals, namely ethanol (50% v/v distilled water), benzalkonium chloride (3% v/v) or Biotin T® v/v), Nd:YAG laser wavelengths (1064 nm 266 nm). The surfaces evaluated 24 h 4 years after cleaning to determine its durability colour spectroph...

according to the english literature, various lasers and light sources (i,g. argon ion lasers, pulsed ktp lasers, diode lasers and nd:yag lasers, pulsed dye laser(pdl), intense pulsed light sources (ipls) are applicable for the treatment of different vascular lesions. these conditions are the most important indication for laser therapy. this review summarizes the current literature on ipl with r...

The paper presents preparation of YAG precursor powders mixture with ability for the reaction sintering at lower temperature. The powder mixture was mechanochemically processed and characterized for the specific surface area and crystallinity (XRD). Sintering experiments were performed on the batched powders, mechanochemically processed powders and as-synthesised YAG powders. XRD measurements a...
