The Radial uses the same hull and fittings as the Laser Standard, but has a smaller sail (5.8 m 2) than the Standard with a different cut, and has a shorter lower mast section. Optimal weight for this rig is 121 to 159 pounds (55 to 72 kg). The Laser Radial rig has a UK Portsmouth Yardstick number of 1150. [9] Its DPN is 96.7. [10]
The Laser Radial or ILCA 6 is a popular one-design class of small sailing dinghy, originally built by Laser Performance and World sailing approved manufactures. It is a singlehanded boat, meaning that it is sailed by one person.
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 ...
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
The procedure results in a decrease in nearsightedness. According to the PERK study, 58% of eyes were corrected within 1.00D of goal 3 years after surgery. Additionally, 76% of eyes had uncorrected vision of 20/40 or better at 3 years. [5] From 2 to 10 years post-operatively 43% of eyes had an increase in farsightedness by 1.00D or more.
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.

The 4.7 uses the same hull and top mast section as the Laser, but has a different, shorter bottom mast section as well as a smaller sail. The bottom mast section is pre-bent which effectively reduces the power of the rig, and the sail is only 4.7 square meters, as opposed to 7 for the Laser Standard or 5.7 for the Laser Radial. (ILCA 6) The ...
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
