Iris Disorders and Reconstruction

Iris disorders may be congenital or caused by trauma, eye surgery or other eye conditions​. They are uncommon but may cause significant visual disability, as well as cosmetic concerns.

Disorders include: 

  • Missing iris (partial iris defects, colobomas or complete absence of iris, known as aniridia)

  • Iris disinsertion ("iridodialysis")

  • Abnormally large pupil​ (fixed, dilated pupil; "mydriasis")

  • Displaced pupil ("corectopia")

  • Multiple pupils ("polycoria")

Due to the relative rarity and complexity of iris disorders, they are frequently overlooked, misunderstood or neglected. Patients may be told that nothing can be done, when in fact solutions often exist.

This patient was referred to me after sustaining a penetrating eye injury. This resulted in a torn iris that was drawn up into a laceration of the white of the eye, traumatic cataract, zonule damage and vitreous prolapse. The vision had reduced significantly to 6/60.

 

I performed combined cataract surgery, vitrectomy and iris reconstruction. After surgery, a nice round pupil was restored and vision improved to 6/5 unaided.

I have spent time working with two world-renowned pioneers in iris reconstruction, Ike Ahmed (Toronto, Canada) and Mike Snyder (Cincinnati, USA), to learn and refine the advanced surgical techniques required for managing these problems. These reconstruction techniques include iris suturing, iris reshaping and prosthetic iris implantation (Morcher segments and HumanOptics CustomFlex Artificial Iris, recently approved by the FDA). 

IMPORTANT:

I do NOT offer iris implants to simply change the colour of your iris for cosmetic reasons. These devices have been shown to cause irreparable damage to otherwise healthy eyes (click link for more info), and I would strongly discourage anyone from pursuing this. They are entirely different from the medically approved devices mentioned above.
