Refractive Surgery Center

The University of California at Berkeley Refractive Surgery Center (RSC) is committed to offering our patients the most recent advancements in laser eye surgery technology to ensure better outcomes and increased safety without compromising quality of care or significantly increasing the cost. Our experienced faculty provide personalized eye care and top notch surgical care. We offer procedures in All-Laser LASIK and Photorefractive Keratectomy (PRK) with Custom Wavefront treatment.

The latest technologies for laser vision correction are employed, featuring the STAR S4 IR™ Excimer Laser System, the iDesign Advanced WaveScan Studio System™, the Intralase iFS™ Laser, and the Oculus Pentacam™. The laser center's convenient location at the Meredith Morgan University Eye Center offers easy access for the public as well as university faculty, staff and students.

RSC Doctor

While UC Berkeley is a teaching institution, the interns only observe our surgical process. Our surgeons, Dr. Andrew Sorenson and Dr. Mira Lim, specialize in cornea and refractive surgery and are fellowship-trained from some of the most prestigious medical schools in the country including Duke University and Harvard. They have over 25 years of combined LASIK and PRK surgical experience. Our Optometric team that evaluates and performs all the pre and post operative care has experience in over 20,000 cases of laser refractive surgery.

We perform a thorough evaluation to determine if you are candidate for laser vision correction. This includes a careful analysis of the cornea using the most advanced equipment, such as the Oculus Pentacam™ HR anterior segment tomography unit. The Pentacam provides a high resolution scan and offers more information about the cornea than most other units available today. It is considered the gold standard in refractive surgery screening. This allows us to screen for subtle corneal abnormalities that make a patient an undesirable candidate for laser vision correction.

RSC Laser Flap Creation

IntraLase Laser Flap Creation

The Intralase Laser™ is the first technology for a truly all-laser, blade-free LASIK procedure, replacing the hand-held microkeratome blade historically used in creating LASIK corneal flaps -- the first step of the procedure -- with a computer-guided, ultra-fast femtosecond laser. This technology provides unparalleled uniformity and precision, biomechanical stability, and an unsurpassed safety profile. The Intralase Laser™ virtually eliminates the majority of the most severe sight-threatening LASIK complications related to use of the microkeratome and, by creating an optimal corneal surface below the flap, provides for better visual outcomes -- taking many patients to 20/20 vision and beyond.

The excimer laser precisely reshapes the cornea under a protective layer of tissue, the flap, using cool ultraviolet light to treat the cornea. The flap is then repositioned and the procedure is complete. Recovery is very quick in the first one to two days and there is minimal discomfort after LASIK surgery. LASIK can correct myopia, hyperopia, and astigmatism.

Some patients may be better suited for Photorefractive Keratectomy (PRK), also known as Advanced Surface Ablation. PRK uses an excimer laser to gently and accurately reshape the surface of the cornea. It is similar to LASIK, but no flap is created. After treatment, a transparent “bandage” soft contact lens is placed over the eye for five to seven days to promote healing. Vision is functional after the first week, however, full visual recovery is typically achieved in 2-3 months. PRK, like LASIK, can correct myopia, hyperopia, and astigmatism. Statistical vision outcomes for PRK are equivalent to LASIK. PRK may be preferred for patients with thinner corneas, dry eyes, and safety concerns due to occupation, sports and hobbies.

Since 2000, the Refractive Surgery Center has proved itself a regional center for excellence in refractive surgery. Our doctors can help you choose the right solution to achieve your vision goals. Our goal is to provide each patient with the facts and resources needed to make the best decision for each individual.

Complimentary consultations are available. For more information, please call (510) 643-2860 to set up an appointment with Dr. Kathy Tran, Chief of the Refractive Surgery Center. We are located in the Meredith Morgan University Eye Center at Minor Hall on the University of California, Berkeley campus.
