IOLs and Alternatives to LASIK Surgery 

IOLs – Intraocular Lenses

There are two parts of the human eye that are responsible for focusing, the cornea and the lens; ophthalmologic medicine has developed ways of modifying each with different kinds of refractive surgery. Portland area doctor Stanley Teplick performs LASIK and Epi-LASIK to treat corneal abnormalities. Refractive surgery options for patients who cannot undergo these procedures or who have other needs include refractive lensectomy and phakic IOLs.

Refractive Lensectomy Surgery

With its basis in the proven techniques of cataract surgery, refractive lensectomy is a procedure that replaces the natural lens of the eye with a prescription intraocular lens, thus reducing the need for glasses and contact lenses.

Before this refractive surgery, your eye will be anesthetized topically or locally. Then your surgeon will make a small, 1/8-inch incision, through which the natural lens is gently removed. Then, the new intraocular lens is inserted into the same small incision and unfolded in place. 

One of the benefits to this kind of refractive surgery is that it does not generally require any sutures. The incision is held closed by the eye’s natural outward pressure, lending itself to a faster healing period than older methods.

Phakic IOLs

Some patients seek the convenience of refractive surgery at our Portland area offices, but are not good candidates for LASIK. These people may be able to take advantage of phakic intraocular lenses (IOLs) at our Portland eye surgery facility. In this procedure, a prescription lens is implanted into the eye without disturbing the existing natural lens.

A benefit of the phakic IOL is that the natural lens can continue to function by maintaining the ability to see up close, thus reducing the need for reading glasses. The procedure itself only takes a few minutes.

For more information about refractive surgery and IOLs, Portland, Bend, Salem, Beaverton, Albany, Vancouver, and other residents throughout Oregon and Southern Washington are invited to contact the offices of Dr. Stanley Teplick today.

There used to only be one type of IOL available  that had correction for your distance vision only, but now the cataract patient has several types of lens available to help with all visual needs including astigmatism and near reading vision.

Monofocal IOL's

Monofocal lenses are the traditional lens correcting your distance vision only.  Patients are not corrected fully if they have more than mild amounts of astigmatism.  Patients will also require reading glasses immediately after surgery.  These lens are covered by Medicare.

Multifocal IOL's

In recent years Multifocal IOL's have been introduced to patients.  These include RESTOR, ReZoom and the Tecnis IOL.  These lenses allow for some near vision assistance and substantially reduce the need for reading glasses.  These lenses can be partially covered by Medicare.

Accommodating IOL's

There is an IOL now available in the United States called the Crystalens that has the ability to correct all ranges of vision using a hinged monofocal lens that moves within the eye like your own natural lens.  The Crystalens can also substantially reduce the need for reading glasses and allows for good intermediate vision as well.  This lens is also partially covered by Medicare.

Toric IOL's

For patients with more than a mild amount of astigmatism there are toric IOL's including the ACRYSOF IQ.  This lens corrects your astigmatism to allow the patient to be glasses free in the distance.  The patient will still require reading glasses after surgery and is partially covered by Medicare.
