Cornea and External Diseases

The Cornea Section is comprised of ophthalmologists who specialize in the evaluation and management of various conditions including:

  • Refractive errors (nearsightedness, farsightedness, and astigmatism)
  • Dry eyes and tear disorders
  • Cataracts
  • Blepharitis
  • Conjunctivitis (infectious and allergic)
  • Ectasias (i.e. keratoconus)
  • Dystrophies (i.e. Fuchs’)
  • Ulcers
  • Benign and malignant tumors
  • Traumatic scars
  • Chemical burns

We have state-of-the-art diagnostic modalities such as:

  • Orbscan
  • Corneal Topography
  • Optical Coherence Tomography (OCT)
  • Specular Microscopy
  • Ultrasonic Biometric Analysis

We offer the latest and advanced surgical procedures for patients with common and complex conditions such as:

  • No stitch cataract surgery
  • Presbyopia-correcting intraocular lens implants (ReSTOR, ReZoom, Crystalens)
  • Astigmatism-correcting limbal relaxing incisions
  • Astigmatism-correcting toric intraocular lens implants
  • Corneal transplantation
  • Combined cataract surgery and corneal transplantation
  • Partial corneal transplantation (lamellar)
  • Endothelial transplantation (DSEK)
  • Limbal stem cell transplantation
  • Phototherapeutic keratectomy
  • Superficial keratectomy
  • Conjunctival autografting
  • Amniotic membrane grafting
  • Artificial cornea (keratoprosthesis)
  • Punctal occlusion/cauterization

Faculty

  • Assistant Professor of Ophthalmology and Visual Science; Residency Director

    Dr. Chow earned her BS at Stanford, and MD at Duke School of Medicine, where she earned an Anlyan Senior Scholarship, received a Howard Hughes research fellowship, and was elected to AOA. Following internship at Kaiser in California, Dr. Chow completed her Ophthalmology Residency at Duke, and was recognized with the Edward K. Isbey, Jr., Resident Award for excellence in clinical care, ethics, and research. She then served a postgraduate year as Chief Resident. She completed her cornea fellowship at the Bascom Palmer Eye Institute in Miami before joining the faculty at Yale. She is the Director of the Cornea and External Disease service at Yale. Dr. Chow’s clinical interests include corneal transplantation (full-thickness penetrating keratoplasty, deep anterior lamellar keratoplasty (DALK), and endothelial keratoplasty (DSAEK and DMEK). She treats a variety of corneal conditions including dry eye, ocular surface disease, graft vs host disease, infectious keratitis, and keratoconus. She also performs cataract surgery with the latest technology including femtosecond laser-assisted cataract surgery and intraoperative aberrometry. Her research interests include medical education. Dr. Chow won the departmental full-time faculty teaching award in 2014 and has served as Residency Program Director since 2014.  She is a member of the American Academy of Ophthalmology (AAO), the Association of University Professors in Ophthalmology (AUPO), and the American Society of Cataract and Refractive Surgery (ASCRS).
