“While laser eye surgery is the most well-known form of vision correction procedure, there are other options for those not suitable for either LASIK, ASLA or SMILE. In fact, there is a vision correction option that would suit 99% of people over the age of 18”
If you have a particularly high degree of refractive error, you may not be suitable for LASIK, ASLA or SMILE. However, if your eyes are in good health and you’re between the ages of 18 and 45, you may be suitable for an implantable lens.
An implantable lens (also called a phakic lens, a collamer lens or an implantable contact lens) works like a contact lens but is surgically inserted just behind the iris or in the space between the cornea and the iris. These lenses can correct high degrees of short-sightedness, long-sightedness and astigmatism.
The artificial lens itself is flexible and is inserted via a micro-incision that a surgeon makes in the side of the cornea. It will then unfurl and be secured in place. There is no need for sutures, as the eye should heal naturally in a matter of weeks.
Unlike laser eye surgery, an implantable lens can be removed at a later stage should a lens procedure (such as cataract surgery) be required.
The natural lens of your eye is highly elastic. This flexibility allows the muscles that support the lens to change shape in order to focus for both distance and near vision. The degree of elasticity and strength of the supporting muscles diminish with age. The result – reading or focusing on items such as a wristwatch or text message becomes more and more difficult. You’ll eventually need a pair of reading glasses.
But there is a surgical option, called lens surgery. It involves replacing the natural crystalline lens of the eye with an artificial lens. Lens surgery is the same procedure as cataract surgery.
The surgeon makes a small incision in the side of the cornea to enable access to the natural lens, which is removed and replaced with an artificial lens. These lenses are selected for the specific vision correction requirements of the patient. Learn more about cataract surgery.
Laser lens surgery involves using a femtosecond laser instead of a blade to create the initial incisions.
The advances in the development of lens implants in recent years have opened up a range of options for those people over the age of 45 who want a surgical solution to reduce their dependency on glasses.
The term monovision actually refers to a concept rather than a procedure. Monovision is the result of a surgeon setting one eye for distance vision and the other for near vision. Click here to learn more.
