Working with an Experienced Laser Centre Team

Thursday, August 20th, 2009

Although it is the surgeon, such as Dr. Raymond Stein,  that will recommend one or more specific procedures, patients benefit from knowledgeable and experienced refractive surgery counselors that provide detailed information and answer questions about refractive options in Toronto. Patients should understand the benefits and risks of the procedures that will provide the best outcome: LASIK, PRK, Refractive lens exchange, Phakic implant (eg Implantable Contact Lens), corneal collagen crosslinking, Intracorneal rings, etc. In many situations there are one or more procedures that can be of benefit to the patient.

The maintenance of an excimer laser and the IntraLase is typically the responsibility of a nonphysician. A laser centre that employs experienced and competent individuals with a low turnover of staff will go a long way to enhance patient outcomes. In the laser room critical data is entered into the computer that drives the excimer laser. It is important that this data be verified by at least two individuals. At the Bochner Eye Institute we have three individuals that confirm the data entry. This ensures that no mistakes will be made and allows for the best possible outcome.

Raymond Stein, MD, Explains Photorefractive Keratotomy

Thursday, August 20th, 2009

Dr. Raymond Stein understands that understanding the different types of vision correction surgery can be confusing for patients. To better understand one option known as Photorefractive Keratotmy, Raymond Stein, MD, has written a short explanation of the procedure.

PRK is a form of laser vision correction that utilizes the excimer laser to enhance vision by altering the shape of the cornea. Although LASIK is the predominant procedure, PRK is indicated in patients with thin corneas, certain superficial corneal dystrophies, and corneas that show some structural weakness. The technique and technology have advanced significantly in recent years. Although the visual recover is slower with PRK than LASIK the final visual outcome is similar. Postoperative discomfort has been dramatically improved by utilizing ice applied to the cornea following the laser ablation. In addition the use of a bandage soft contact lens and nonsteroidal drops greatly enhances comfort. Postoperative corneas are usually clear with the use of a single application of Mitomycin C drops. This is a chemotherapeutic agent that inhibits the laying down of new collagen that contributes to corneal haze. Advances in laser technology with flying spot lasers at a fast delivery rate that utilize large optical zones enhance the visual outcome. The large optical zones achieved with the Allegretto laser inhibit the corneas healing response and decrease regression.

Pterygium Surgery by Dr. Raymond Stein

Monday, August 10th, 2009

A pterygium is a benign growth of the conjunctiva that grows onto the cornea. The etiology of this growth is thought to be related to UV light exposure and/or wind. A pterygium can be of cosmetic concern and/or result in diminished vision because of the induction of irregular astigmatism. Over the past 15 years I have utilized a technique of removal combined with a topical agent called Mitomycin C. This is a chemotherapeutic medication that dramatically reduces the recurrence rate. After the growth is removed under local anesthesia, Mitomycin C is applied to the area for 1 minute. This medication inhibits tissue growth which accounts for the low recurrence rate. Previous methods of removal were associated with a 50% recurrence rate. The technique I have used is associated with a 95% success rate. Patients with a recurrence can have additional surgery with a high chance of success.

Night Vision and Laser Vision Correction in Toronto by Raymond Stein MD

Monday, August 10th, 2009

Over the past 6 years our laser vision correction patients have reported better night vision than what they experienced with their previous glasses or contact lenses. This improvement is related to the large optical zones that are utilized with the Allegretto laser. Previous laser systems were limited to a 6 mm optical zone. The Allegretto consistently provides an optical zone close to 9 mm. In addition to the broad area of treatment the Allegretto laser reduces the induction of spherical aberration to improve vision quality. Spherical aberration is considered one of the most important higher aberrations that can degrade night vision. The Allegretto improves the corneal curvature so that both peripheral and central light rays that pass through the pupil are focused on the retina. This customized treatment enhances the quality of night vision.

Dr. Raymond Stein proudly features many leading-edge technologies in Toronto, including the iFS Femtosecond Laser

Thursday, August 6th, 2009

ifs-laser-smallDr. Raymond Stein proudly features many leading-edge technologies, including the iFS femtosecond laser in Toronto for highly precise corneal flap creation. Dr. Raymond Stein recognizes that the creation of an extremely thin, smooth corneal flap is crucial in delivering the best possible vision correction results. To provide patients with the most advanced flap creation procedures, he has incorporated the iFS femtosecond laser at the Bochner Eye Institute practice.

iFS Difference
The iFS platform integrates many sophisticated measurement and control systems that enhance the safety and precision of the corneal flap creation procedure.  The iFS femtosecond laser also operates at a very high speed, exposing the cornea to a smaller amount of laser energy. Consequently, the risk of inflammation following Laser Vision correction surgery is greatly reduced.
