Surgery for Presbyopia

Presbyopia is a common age-related condition in which near vision worsens due to the hardening of the lens of our eye. It causes people to have difficulty reading and performing other tasks that require sharp and focused close vision.

Symptoms begin around the age of 40 when you begin to see people with untreated presbyopia holding books, magazines, newspapers, and menus at arm’s length in order to focus properly and avoid eye strain. Other symptoms include headaches or fatigue when trying to focus on something at close range.

Causes of Presbyopia

During our youth, the lens of our eye and the muscles that control it are flexible and soft, allowing us to focus on close objects and shift focus from close to distant objects without difficulty. As the eye ages however, both the lens and the muscle fibers begin to harden, making near vision a greater challenge.

Surgical Treatment for Presbyopia

The most common form of treatment for presbyopia is wearing reading glasses, bifocals or progressive lenses. Bifocal and multifocals are also available in contact lenses for those who prefer to be glasses-free. A third option, however, is a number of surgical procedures that allow you the freedom of correcting your near vision without the use of glasses or contact lenses.

LASIK

Monovision LASIK

Monovision is a technique that began with presbyopia-correcting contact lenses designed for individuals with presbyopia and nearsightedness or astigmatism. Each eye gets a different lens power – one lens is used in the dominant eye to correct for distance vision and the other for near vision. The eyes adapt to the two lens powers by learning to use the appropriate eye for the necessary distance power. Monovision LASIK surgery is based on the same principle of correcting each eye for a different refractive power and has shown just as high if not higher success rates than the contact lens technique. Usually, patients will try out monovision with contacts first to ensure that it works and that the eyes adapt properly.

PresbyLASIK

PresbyLASIK is a procedure that is currently available in Canada and Europe and undergoing clinical trials in the United States. As opposed to monovision LASIK, this procedure is a multifocal alternative in which different rings of refractive power are created on the cornea, similar to multifocal lenses. This provides vision correction at all distances simultaneously.

Conductive Keratoplasty (CK)

Conductive Keratoplasty uses radio waves via a hand-held instrument to mold the corneal surface to improve near vision. The procedure can be done on one eye using the monovision principle and is a good solution for those that do not need vision correction for nearsightedness or astigmatism. The effects of CK, however are not permanent and the improvement in near vision will diminish over time.

Corneal Inlays or Onlays

Corneal inlays and onlays involve surgically implanting a small lens into the eye to increase focus and near vision. The distinction between inlays and onlays is in where the lens is placed on the eye.

Refractive Lens Exchange

In refractive lens exchange the eye’s hardened lens is replaced with an artificial lens called an intraocular lens (IOL) to provide multifocal vision. This surgery is similar to and often done in conjunction with cataract surgery.

To our valued patients,

During these challenging times, we feel it’s especially important to keep you informed of what we are doing to keep you safe. The health and safety of our patients is our primary goal. The impact of the COVID-19 pandemic remains fluid and as such we have made the following changes in our clinic as we strive to maintain the highest standards of care for you our patients:

* Modified schedule. Anyone entering the clinic will need an appointment. There will only be one patient allowed in the clinic at one time to ensure social distancing. Other family members are not permitted in. You can continue to call the clinic to make these appointments. Seniors 60 and over will kindly be asked to reschedule for a safer time in the future.

* All patients must sign a form declaring that they do not have a fever, sore throat, cough, runny nose and other flu-like symptoms including aches and pains. They also must declare that they are practicing social distancing in accordance with the Governor of Washington’s mandate.

* All common surfaces will be disinfected in accordance with current guidelines and protocols after each and every patient and before a new patient enters the clinic. This includes instruments and eyeglass frames that have been handled.

Thank you for your patience and understanding during this difficult time. Our thoughts and prayers are with you. Together, we will get through this.

Warmest regards,

Dr. Osborne and staff
