EVO ICL™ (Implantable Collamer Lens)

EVO ICL™ (Implantable Collamer Lens) surgery involves putting an artificial lens in the eye. Unlike RLE, the natural lens is not removed, and the artificial lens is placed between the natural lens and the iris.

EVO ICL™ can correct nearsightedness and astigmatism. It is sometimes referred to as an implantable contact lens.

Cataract Surgery

Cataract eye surgery is a very common and medically necessary procedure to remove and replace the eye’s natural lens when the vision has been clouded by a cataract. We offer laser-assisted cataract surgery and lifestyle lenses as options for our patients.

Other Procedures

Contoura® Vision LASIK

Contoura® Vision is a topography-guided LASIK treatment designed to provide a more personalized laser procedure for patients with nearsightedness, or nearsightedness with astigmatism, based on the unique corneal topography of each eye. Contoura® Vision creates a Highly Precise and Accurate map of a patient’s eyes measuring up to 22,000 unique elevation points on each eye.

Refractive Lens Exchange (RLE)

Refractive lens exchange (RLE), is when a clear lens is implanted to replace your eye’s natural lens to correct your vision.

This procedure is often used for pre-cataract patients, as a preventative vision correction solution. RLE can also correct nearsightedness, farsightedness, and astigmatism.

Pterygium Surgery

Pterygium eye surgery is performed under topical anesthesia on an outpatient basis.

Laser Blepharoplasty

Cosmetic Treatments

Nonsurgical cosmetic treatments can be used for both enhancing natural features or for medical reasons.

Argon Laser Treatments

Argon Laser Trabeculoplasty (ALT) is the most common surgery performed for open-angle glaucoma. ALT helps fluids drain from the eye, reducing intra-ocular pressure that can cause damage to the optic nerve and loss of vision.

Laser Iridotomy

Laser iridotomy is used in the treatment of acute angle-closure glaucoma. A doctor uses a laser to cut open a small hole in the iris, allowing built-up intraocular fluid to drain out and restore normal pressure levels to the eye.

Eye Stent or Hydrus

Hydrus is a micro-stent. It is placed in the eye as a spacer for your natural fluid drainage channels.

Cornea Transplantation

When irreversible damage to the cornea is caused, from either infection or trauma, corneal transplant or Keratoplasty may be the ideal option.


Canaloplasty is a surgery for the reduction of intraocular pressure in patients with glaucoma.

Selective Laser Trabeculoplasty (SLT)

If eye drops and oral medications are not successfully lowering the eye pressure in patients with glaucoma, a doctor might discuss selective laser trabeculoplasty (SLT) with the patient. This can also be used as the first treatment for glaucoma.

Chalazion Surgery

Chalazion surgery involves removing a small lump (a chalazion) that develops on the eyelid.


These are medical conditions that affect your eyelid.
