Once implanted, IOLs have three major benefits. First, they are an alternative to the excimer laser procedure (LASIK), a form of eye surgery that does not work for people with serious vision problems. Effective IOL implants also eliminate the need for glasses or contact lenses post-surgery for most patients. [5]
Goggles come in two styles, eyecup goggles, and cover goggles. Eyecup goggles completely cover the eye socket to give all-round protection. They have adjustable or elasticized headbands and often are equipped with ventilation ports to allow air in and prevent fogging. For example, swimming goggles to protect the eyes from salt or chlorine ...
LASIK can correct myopia up to -12 to -14 D. The higher the intended correction the thinner and flatter the cornea will be post-operatively. For LASIK surgery, one has to preserve a safe residual stromal bed of at least 250 μm, preferably 300 μm. Beyond these limits there is an increased risk of developing corneal ectasia (i.e. corneal ...
LASIK surgery is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap to expose the corneal stroma and then an excimer laser to reshape the corneal stroma in order to improve visual acuity. [2] [3] LASIK is very similar to another surgical corrective procedure, photorefractive keratectomy (PRK ...
Laser Blended Vision can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery PRK or LASEK can be used to produce the effect. Laser Blended Vision works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration . [ 2 ]

Such implants have no direct attachment to the ocular prosthesis. [6] Usually, these implants are covered with a material that permits fixation of the extraocular recti muscles, such as donor sclera or polyester gauze which improves implant motility, but does not allow for direct mechanical coupling between the implant and the artificial eye. [7]
The protective specifications (wavelengths and optical densities) are usually printed on the goggles, generally near the top of the unit. In the European Community, manufacturers are required by European standard EN 207 to specify the maximum power rating rather than the optical density. Always wear safety goggles.
