Practice Philosophy

Care model emphasizing advanced, subspecialty-level medical and surgical eye care designed to handle both routine and complex cataract, cornea, and glaucoma conditions.
Treatment philosophy focused on individualized, evidence-based plans that match technology (LASIK, PRK, ICL, CXL, MIGS, premium IOLs) to each patient’s diagnosis, risk profile, and lifestyle.
Patient education prioritized through detailed procedure pages, LASIK self-testing, vision-correction information, and consults that explain options (including when standard lenses or more conservative choices are sufficient).
Long-term eye health and vision outcomes are supported by ongoing follow-up for glaucoma and corneal disease, attention to surgical durability, and continued professional education and research involvement by key surgeons.

Treatment and Service Offerings

Comprehensive & Preventive Eye Care

Comprehensive eye examinations provide refraction, ocular health assessment, and screening for cataracts, glaucoma, corneal disease, and refractive errors.
Medical eye evaluations address symptoms such as blurred vision, halos, eye pain, or pressure, with escalation to surgical planning when indicated.
Pre- and post-operative care is coordinated with surgeons for cataract, glaucoma, refractive, and corneal procedures across multiple locations.

Refractive & Vision Correction Services

LASIK eye surgery uses computer-controlled excimer laser corneal reshaping to treat myopia, hyperopia, and astigmatism via a minimally invasive, outpatient procedure.
PRK (photorefractive keratectomy) offers a surface ablation alternative to LASIK for patients with thinner corneas or specific anatomic considerations.
The LASIK self-test provides online screening to help patients understand candidacy before an in-office evaluation.
Implantable Collamer Lens (ICL) provides internal lens-based refractive correction for suitable patients, especially those with higher refractive errors or thinner corneas.

Cataract & Lens Surgery

Cataract surgery performs small-incision phacoemulsification with intraocular lens implantation as an outpatient procedure.
Advanced cataract techniques utilize high-end phaco platforms and surgeon expertise for complex cases and combined cataract and glaucoma surgery.
Premium lens options offer multifocal, accommodating, and astigmatism-correcting (toric) IOLs tailored to lifestyle and visual goals.
Complex cataract surgery manages cases with prior ocular surgery, coexisting corneal disease, or glaucoma via subspecialty surgeons.

Glaucoma Services

Glaucoma evaluation conducts comprehensive assessments for open-angle and angle-closure glaucoma, including history, exam, and risk stratification.
Medical glaucoma management utilizes pressure-lowering eye drops and monitoring for disease stability.
Minimally invasive glaucoma surgery (MIGS) includes options such as iStent, Hydrus, OMNI, KDB, GATT, Micropulse, and Diode CPC in appropriate candidates (based on fellowship training).
Laser glaucoma procedures provide Selective Laser Trabeculoplasty (SLT) and other laser treatments as part of staged glaucoma care.

Cornea & Ocular Surface / Cross-Linking

Cornea surgery addresses corneal disease with treatments ranging from pterygium and superficial procedures to full corneal transplantation.
Corneal cross-linking (CXL) employs UV light and riboflavin-based therapy to strengthen corneal collagen in conditions like keratoconus and post-LASIK ectasia.
Corneal transplant procedures include advanced lamellar and penetrating techniques (DMEK, DSAEK/DSEK, DALK, PKP, artificial cornea) via fellowship training.

Additional Diagnostic & Supportive Services

Surgical consultations provide second opinions and detailed counseling regarding cataract, glaucoma, and corneal treatment options.
Video and blog resources offer patient-facing education on eye conditions, surgical options, and post-operative expectations.

Proprietary Techniques & Treatment Protocols

Early adoption and leadership in ICL and DSEK feature surgeon experience as the first fully certified Staar ICL fellow in the U.S. and the first U.S. surgeon to perform ultra-thin DSEK.
Comprehensive corneal transplant portfolio integrates modern lamellar techniques (DMEK, DSAEK/DSEK, DWEK, DALK, artificial cornea) with standard PKP for individualized corneal rehabilitation.
The advanced glaucoma algorithm combines medical therapy, SLT, a broad range of MIGS options, and complex glaucoma surgery, guided by fellowship training and participation in the Interventional Glaucoma Consortium.
Cross-linking–centered keratoconus care utilizes corneal cross-linking with specialty contact lens co-management (including scleral lenses) to stabilize corneal disease and optimize vision.
Structured refractive workflow uses LASIK self-testing, detailed measurements, and surgeon-specific expertise (LASIK, PRK, SMILE, ICL) to match each patient with the most appropriate vision correction procedure.
