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.

After surgery, to prevent contamination, the eyes should not be rubbed and the use of eye makeup, face cream or lotions should be avoided. Excessive dust, wind, pollen or dirt should also be avoided. Sunglasses should be worn on bright days because the eyes will be more sensitive to bright light for a while.
Contact lens-assisted cross-linking (CACXL) may be performed for people with corneal stromal thickness between 350 μm to 400 μm after epithelial removal. in this method a pre-corneal riboflavin film, a riboflavin-soaked UV barrier-free soft contact lens of negligible power and a pre-contact lens riboflavin film are used to decrease UV ...
Cataract surgery by “couching” (lens depression) is one of the oldest surgical procedures. The technique involves using a sharp instrument to push the cloudy lens to the bottom of the eye. Perhaps this procedure is that which is mentioned in the articles of the Code of Hammurabi (ca. 1792–1750 BC) though it is a mere speculation.
to correct refractive errors of the eye; not invasive Contact lenses: to correct refractive errors of the eye; a little invasive Phoropter: used in refraction testing Tonometers: used to determine the intraoccular pressure (IOP) - useful in glaucoma; video link for various types of tonometers. Speculum: to keep the eyes open during any operation
The retrobulbar block is performed with the patient either seated or supine and looking straight ahead. The head should be maintained in a neutral position. A needle (22–27 Gauge, 3 cm long) is inserted at the inferolateral border of the bony orbit and directed straight back until it has passed the equator of the globe.
The procedure may also reduce the chances of dry eye symptoms after surgery. Due to the PRK procedure not requiring a surgical flap, athletes or individuals concerned with trauma introduced by the flap may see benefits to LASEK. Patients that wear contact lenses will typically need to stop wearing these for a specified time before the procedure ...
Limbal relaxing incisions (LRI) are a refractive surgical procedure to correct minor astigmatism in the eye. Incisions part way through the cornea are made at one side or at opposite edges of the cornea, following the curve of the iris, causing a slight flattening of the cornea in that area. [1]
