  2. LASIK - Wikipedia

    en.wikipedia.org/wiki/LASIK

    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 ...

  3. Laser blended vision - Wikipedia

    en.wikipedia.org/wiki/Laser_blended_vision

    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 ]

  4. Photorefractive keratectomy - Wikipedia

    en.wikipedia.org/wiki/Photorefractive_keratectomy

    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 ...

  5. FDA Warns of Potential Side Effects Associated With LASIK Surgery

    LASIK is a surgery that is used to correct refractive errors, such as far-sightedness, near-sightedness, and astigmatism, so that people can be less dependent on glasses and contact lenses to get ...

  6. Small incision lenticule extraction - Wikipedia

    en.wikipedia.org/wiki/Small_incision_lenticule...

    In some cases post operative tear secretion and dry eye syndrome have been observed along with similar post operative complications seen in LASIK surgery. [1] [6] As lenticule extraction techniques evolve, there is a possibility that extracted lenticules can be cryogenically preserved either for future donation, [9] or re-implantation. [1]

  7. Phakic intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Phakic_intraocular_lens

    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 ...
