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.

PROTECTING OUR COMMUNITY

We have been working very hard to prepare to re-open for normal "routine" preventive eye care, taking every precaution to ensure the safety of everyone involved. We are pleased to announce as of Monday May 18th we'll be seeing patients for all types of eye care, including routine annual eye exams.

But, things will be very different than they were prior to the pandemic.

1. Our front door will be locked at all times. We will be allowing only 1 person at a time in the office and by appointment only, so please enter alone, or with no more than l other person accompanying you. Others may wait in the car.

2. Masks will be required for both patients and us while in our office.

3. Upon entering, we will be checking your temperature and screen you for COVID symptoms or possible exposure. If your temperature is 100 F or higher, or you have symptoms or may have recently been exposed to COVID, we will reschedule you.

4. We will need you to respect the 6 feet personal distancing while outside the exam room

5. We will have you wash your hands for 20 seconds or use hand sanitizer when you enter. We will be using hand washing and hand sanitizer constantly and will be disinfecting everything you and we touch. Please don't touch anything that isn't absolutely necessary.

6. For frame selection or picking out glasses, please let us help you, and don't just browse and try on frames by yourself. We have to disinfect the frames every time they are touched or worn, and we need to know which frames need to be disinfected.

We are doing all these things to protect you and all of our other patients as best we can. We will need and depend on your cooperation on this during this very difficult time. Doing so will protect your fellow patients-many of whom are at extremely high risk if they contract COVID - and to protect us. All healthcare providers are putting themselves in harm's way every day during this pandemic - the more we all cooperate and take appropriate precautions, the better off we all will be.

We are all in this together. Thank you for your patience, understanding, and cooperation.

Please stay safe.

Dr. Jim Hutchins and staff
