Phacoemulsification at King Khaled Eye Specialist Hospital--the experience of the past

publication date

Abstract/Introduction

Objective: To study the outcome of phacoemulsification (PE) compared to standard extracapsular surgery before the introduction of state-of-the-art techniques (capsulorhexis, hydrodissection, nuclear cracking, nuclear chopping, sutureless incisions) and sophisticated equipment.

Study design: Charts from 375 patients (453 eyes) undergoing PE between 1984 and 1989 were randomly selected and studied retrospectively. A minimum age of 35 years, and a minimum follow-up of three months were required.

Setting: A large eye hospital in the Kingdom of Saudi Arabia staffed with an international faculty of ophthalmic surgeons.

Patients: Patients over 35 years of age undergoing PE for immature, mature and traumatic cataract.

Main outcome measures: Postoperative visual acuity, and rate or frequency of intraoperative complications.

Conclusion/Results

Results: 66.5% achieved visual acuity of 20/40 or better, which compares favourably with the 36.5% of eyes reaching this level of visual acuity after mainly standard extracapsular cataract surgery in another study at our hospital. Posterior capsule ruptures occurred in 7.5% and vitreous loss in 5.5%. Other ocular disease (odds ratio 7.51 confidence interval 4.43-12.7) and intraoperative complications (odds ratio 2.97 confidence interval 1.38-6.42) were statistically significant predictors for final visual acuity of under 20/40 (p = < 0.001 and 0.005 respectively).

Conclusion: The outcome of PE was better than that of standard extracapsular cataract extraction in the same setting. However, since PE appeared to be used selectively, no clear advantage compared to extracapsular cataract extraction is evident in the period before the introduction of modern state-of-the-art PE-techniques.

Testimonials

Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.

I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.

Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.

Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
