The intrastromal corneal ring (ICR) is designed to correct mild-to-moderate myopia by flattening the anterior corneal curvature without encroaching on the visual axis. (medscape.com)
For patients with moderate to high myopia or thin corneas which cannot be treated with LASIK and PRK, the phakic intraocular lens is an alternative. (lougheedoptical.com)

It reduces the chances of pressure by the lens haptics and the optic on the natural lens and the iris, in case a bigger knuckle of iris is drawn inside the claw. (medscape.com)
The eye's natural lens is usually replaced with an artificial intraocular lens (IOL). (wikipedia.org)
The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) to restore focus within a useful range of distances. (wikipedia.org)
They sit right in front of the natural lens and help the eye focus light onto the retina, which allows far away objects to be seen clearly. (tablemountaineyecare.com)
The natural lens is removed, and a synthetic lens is put in its place. (tablemountaineyecare.com)
The lens may be implanted either in front of or behind the iris, and it works with the eye's natural lens to correct refractive errors. (2020detroit.com)
The term phakic means to implant a lens into the eye without removing the eye's natural lens. (2020detroit.com)
The natural lens typically does not need to be removed. (myvision.org)
In refractive lens exchange, the ophthalmic surgeon removes the noncataractous natural lens of the eye with or without intraocular lens placement. (medscape.com)
However, when used as implantable contact lenses they work in conjunction with the natural lens of the eye in order to correct your vision. (paloaltoeyes.net)
The ICL is then inserted through the incision and placed either in front of or behind the iris which is the colored part of your eye and in front of the natural lens. (paloaltoeyes.net)
Under an operating microscope and with Phaco-emulsification machine a small cut is made in the eye and cloudy lens is removed and plastic Intra-ocular Lens is placed in place of natural lens. (amdavadeyelaser.org)
They are micro thin lenses implanted over the natural lens, inside the eye, to correct spectacle power. (ravieyefoundation.in)

assessments of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refractive error, axial length, intraocular pressure, corneal endothelial cell density, and vault were conducted, and a questionnaire was administered. (biomedcentral.com)

Risk factors contributing to shorter survival resulting from ECL were a smaller ACD, lower endothelial cell density, and implantation with an Artisan hyperopia (toric) or Artiflex myopia (toric) IOL. (tue.nl)
I rotated the Toric ICL according to the lens? (crstoday.com)
I had prelex operation with trifocal toric lens. (whatclinic.com)

2 If corneal lenses are not successful, hybrid (rigid center with a soft skirt), toric, bitoric, KC design soft contact lenses, KC design corneal contact lenses, piggy-back, and scleral lenses may be valuable alternative options. (contactlensupdate.com)
The toric IOL is a lopsided lens to compensate for the lopsided cornea. (healthscopemag.com)

Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision. (wikipedia.org)
An insertion of a phakic intraocular lens is done without the extraction of the crystalline lens. (blueeye.it)
This operation of substituting the transparent crystalline lens to correct a visual impairment is technically the same operation that we perform in case of the extraction of a cataract, except that in the latter case the crystalline lens is not transparent but opaque, and the role of the intervention is mainly to erase opaqueness and then to correct the visual impairment. (vistavisiongroup.net)
The lens is inserted through a micro incision in the cornea and positioned behind the iris and in front of the crystalline lens. (bochner.com)
Near vision remains unchanged, unlike with a refractive lens exchange in which the crystalline lens of the eye is replaced with an artificial lens. (bochner.com)
Narrow distance between the cornea and the crystalline lens of the eye. (bochner.com)

The main outcome measures were manifest refraction, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), endothelial-cell count (ECC), intraocular pressure (IOP), and adverse events. (paojournal.com)

LASIK cases number more than three million a year at this point," he says. (medscape.com)
high myopia, ineligible for LASIK برای وی مناسب نمی‌باشد. (drsiamakzarei.com)
For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses. (lougheedoptical.com)
In some cases, your vision after LASIK may be permanently less clear than it was with glasses before LASIK. (lougheedoptical.com)
In normal circumstances and conditions LASIK can reduce your dependence on glasses and almost always gives you the ability to function well without the need for glasses or contact lenses. (lougheedoptical.com)
I elect to perform LASIK instead in approximately 14% of these patients, and in about 8% of cases a second laser enhancement is necessary. (crstodayeurope.com)

Cataracts form when clumps of proteins or yellow-brown pigment accumulate in the lens, which reduces transmission of light to the retina at the back of the eye. (wikipedia.org)
About 20 million people worldwide are blind due to cataracts, which cause 51% of all cases of blindness and 33% of visual impairment. (wikipedia.org)
Most often the result of aging, cataracts are a clouding of the lens (the part of the eye that focuses light, resulting in sharp and clear visual images). (healthscopemag.com)

To the benefit of many people, the past five years have seen new developments in lens options to correct refractive errors, including multifocal lenses, accommodative lenses and monovision lenses. (healthscopemag.com)

The cornea and lens fix the image in sharp focus on the retina, which is the delicate section of the eye and acts as a "film" that coats the back of the eyeball. (blueeye.it)
If instead, the light rays focus on the front of the retina, rather than on it, myopia is developed. (blueeye.it)
In a normal eye, the flexibility of the lens, the curvature of the cornea and the length of the eye work together to produce a clear image on the retina. (northvalleyeyecare.com)
The purpose of these lenses is to divert light rays in such a way that these focus exactly on the retina. (vistavisiongroup.net)
Phakic lenses enable light to focus properly on the retina for clearer vision without corrective eyewear. (drsiamakzarei.com)
So the light is not focused on the retina through lens which leads to blurring of vision. (amdavadeyelaser.org)
The light image is focused onto the retina by both the cornea and the lens . (hdkino.org)
