14th Winter European Cataract and Refractive Surgery (ESCRS)


The 14th Winter European Cataract andRefractive Surgery (ESCRS) was held Feb.12th to 14th in Budapest, Hungary

I not only attended but also participated with my presentation onBroad-beamlaserSuperficial PRK.     

The Intralasik laser was developed in Budapest13 years ago, with expert advice provided by Prof. Fyodorov and Dr. Kodo Okuyama.

It was wonderful to meet my old colleagues and reminisce.




28th European Cataract and Refractive Surgery (ESCRS)


The 28th European Cataract and Refractive Surgery (ESCRS) was held Sept.4th to 10th in Paris, France

There was a memorial lecture and ceremony to celebrate the 25th.anniversary of PRK and the 20th anniversary of LASIK which was in memory of the late Prof. Fyodorov.

Prof. Fyodorov is regarded as the father of modern eye surgery.

Sangubashi Eye Clinic participated in the E-poster session, to demonstrate the practical use and functionality of Prof. Fyodorov s Broad beam laser and its ability to create a multi focal refractive surface.

Since I was operated on 27 years ago by Prof. Fyodorov, I can safely say that having the ability to create a multi focal refractive surface is the most unique point of my operation. Doctors need to think about the long term effects and outcomes of their operations not just the short term gains.


Summary of the Paris 2010 E-poster ESCRS

Title:Transepitherial PRK can be used to create a multi focal refractive surface

Purpose: To report a case of spectacle-free reading in presbyopic patient post transepitherial PRK.

Venue Sangubashi Eye Clinic Refractive Keratoplasty Tokyo,Japan. PhD.M.D.Kodo Okuyama.

Methods: A 47 year old man, who had his left eye operated on using transepitherial PRK 5 years ago, in 2005. His right eye has not been operated on and he has continued to use the same power contact lens. Use of the Profile 500 created by the Fyodrov Institute for the transepitherial PRK. Keratotopography TMS-N and other routine exams pre and post refractive surgery.

Results: Pre operative data for the left eye SE -6.00D / BCVA 1.2 / UCVA 0.03 in distance. Post operative data at 5 years, for the left eye: SE -0.75D / BCVA 1.2 / UCVA 0.9 in distance. Near vision 0.5 at 40 cm. The un-operated right eye using a contact lens -5.00D / BCVA 1.2 / UCVA 0.05 in distance. Now, near vision with contact lens is 0.3 and without contact lens 0.7 at 40 cm. The karatotopogram of the left eye shows the three post operative corneal zones:

1. Central zone: mostly blue color indicating a less refractive power zone.

2. Para central zone: light green ring indicating a small refractive power zone.

3. Peripheral zone: yellow to reddish ring indicating a high refractive power zone.

Conclusions: Post operated left eye using transepitherial PRK was successful with both near and far vision. This finding leads me to hypothesize that I have created an aspheric refractive multi focal corneal surface similar to a multi focal refractive IOL.

Financial Disclosure: I do not receive any financial support.
