Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.
Yttrium aluminium garnet laser (YAG laser) to correct posterior capsular opacification (specially after removal of a cataract, if required), peripheral iridotomy, retinal surgery, laser-assisted sub-epithelial keratectomy [4] etc. Electrolysis: used for permanent hair removal Electrocautery: for electrosurgery Phacoemulsification
Laser blepharoplasty is the performance of eyelid surgery using a laser instead of a scalpel. Laser blepharoplasty is often combined with laser eyelid rejuvenation, as the two procedures can be performed in conjunction. A CO 2 laser blepharoplasty offers many benefits over a blepharoplasty performed using a scalpel. Some of these benefits ...
The Hughes procedure is an oculoplastic procedure which is performed to reconstruct a lower eyelid defect. It is usually performed as a 2-stage procedure. [1] [2] The most common use for the Hughes procedure is reconstruction after the removal of a lower eyelid skin cancer. [3] The result aims to recreate the normal appearance and function of ...
Laser photocoagulation can help prevent the deterioration of some retinal disorders and reduce the risk of future vision loss, but it cannot restore vision once it has been lost. The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes.
In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer. Opening the globe for a surgical iridectomy in a patient with high intraocular pressure greatly increases the risk of suprachoroidal hemorrhage , with potential for associated expulsive hemorrhage .
The small incision lenticule extraction (SMILE) procedure was first published in 2011 by Walter Sekundo et al. [7] [10] Various modifications of the procedure have since then been described which aim to reduce the duration of the procedure, reduce the risks of the lenticules being incorrectly cut or make the procedure easier to learn.

With PRK, the corneal epithelium is removed and discarded, allowing the cells to regenerate after the surgery. The procedure is distinct from LASIK (laser-assisted in-situ keratomileusis), a form of laser eye surgery where a permanent flap is created in the deeper layers of the cornea. However, PRK takes longer to heal and can, initially, cause ...
