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. Universal eye speculum.
Descemet membrane endothelial keratoplasty ( DMEK) is a method of corneal transplantation. The DMEK technique involves the removal of a very thin sheet of tissue from the posterior (innermost) side of a person's cornea, replacing it with the two posterior (innermost) layers of corneal tissue from a donor's eyeball.
Anatomical terminology. [ edit on Wikidata] The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. [1] [2] In humans, the refractive power of the cornea is ...
Photorefractive keratectomy ( PRK) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis [1]) ( LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses. LASEK and PRK permanently change the shape of the anterior central cornea using an excimer ...
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the anterior curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power , [1] its topography is of critical importance in determining ...
Eye surgery. Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent ...
Corneal reshaping. ICD-9-CM. 11.71. [ edit on Wikidata] Keratomileusis, from Greek κέρας (kéras: horn) and σμίλευσις (smíleusis: carving), [1] or corneal reshaping, is the improvement of the refractive state of the cornea by surgically reshaping it. It is the most common form of refractive surgery. The first usable technique was ...
Corneal pachymetry is the process of measuring the thickness of the cornea.A pachymeter is a medical device used to measure the thickness of the eye's cornea.It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.
