  2. Intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens

    An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery.

  3. Cataract surgery - Wikipedia

    en.wikipedia.org/wiki/Cataract_surgery

    Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1] The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.

  4. Phakic intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Phakic_intraocular_lens

    A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.

  5. Multifocal intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Multifocal_intraocular_lens

    Monofocal lenses are standard lenses used in cataract surgery. People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2]

    It also provides the intraocular lens implant with the ideal place to be located in the eye, away from contact with other structures yet securely held in place. [ 11 ] The surgeon removes the anterior face of the capsule that contains the lens inside the eye, tearing a circular opening in the front surface of the lens capsule to access the lens ...

  7. Intraocular lens power calculation - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens_power...

    The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the ...

    For HA implants drill 1 mm holes as muscle insertion site; Draw Tenon's fascia over implant; Close Tenon's facia in one or two layers; Suture conjunctiva; Insert temporary ocular conformer until prosthesis is received (4–8 weeks later) After implant vascularization, an optional secondary procedure can be done to place a couple peg or post.

  9. Iris-fixated intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Iris-fixated_intraocular_lens

    Iris-fixated intraocular lens is an intraocular lens that is implanted surgically into the eye and attached to the iris. Originally developed for aphakia, phakic versions have also been produced to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. They are suited for correction of eyes where corneal refractive ...
