Clinical Specialties & Surgical Expertise
Refractive & Custom Vision Correction Surgery
- LASIK & Custom Laser Vision Correction: Tailored refractive procedures designed to reduce or eliminate reliance on glasses and contacts.
- Refractive Lens Exchange (RLE): Also known as Custom Lens Replacement, RLE replaces the eye’s natural lens with an advanced intraocular lens to correct high farsightedness, nearsightedness, or presbyopia before cataracts develop.
- EVO ICL (Implantable Collamer Lens): Advanced vision correction solutions for patients who may not be ideal candidates for LASIK.
- Corneal Cross-Linking (Epi-On): Offering cutting-edge, minimally invasive epi-on corneal cross-linking utilizing the Glaukos system to treat keratoconus and preserve corneal integrity with faster recovery times.
Advanced Cataract & Custom Lens Implants
- Laser Cataract Surgery: Utilizing precision femtosecond laser technology to enhance surgical safety and visual outcomes.
- Advanced Technology Intraocular Lenses (IOLs): Expert fitting and implantation of multifocal, extended depth-of-focus (EDOF), and toric intraocular lenses tailored to each patient’s unique lifestyle and visual goals.
Comprehensive Glaucoma Management
- Minimally Invasive Glaucoma Surgery (MIGS): Advanced microsurgical techniques performed during or independent of cataract surgery to reduce intraocular pressure.
- Sustained-Release Drug Delivery (Durysta®): In-office tiny biodegradable implants that release glaucoma medication continuously inside the eye, helping patients lower intraocular pressure without relying on daily eye drops.
- Laser Glaucoma Therapies: Targeted outpatient laser procedures designed to preserve optic nerve health and slow disease progression.

“Every eye is unique, and so are the visual needs of every patient. My priority is to provide personalized, technologically advanced surgical solutions that empower my patients to live active, vibrant lives without the barrier of compromised sight.”
