Abstract Details

Purpose:

To alleviate diplopia and severe glare symptoms from an iris defect that resulted following primary wound repair in a patient who sustained a penetrating eye injury with a glass foreign body, using the Iris Prosthetic System (IPS) in-the-bag fixation Implant.

Setting:

Outpatient clinic consultation followed by surgical intervention in the operating theatre, Ophthalmology Department, Kettering General Hospital NHS Foundation Trust, Kettering, Northamptonshire NN16 8UZ, United Kingdom.

Methods:

Mr AS, a 33 years old gentleman was reviewed in the clinic when he presented with a history of severe glare, double vision and a vision of 6/18 in the affected left eye. He had a history of primary wound repair for a penetrating injury to the left eye with a glass foreign body (smashed car window). Having tried contact lenses unsuccessfully, he was keen on iris plate implantation. He underwent a cataract extraction under a general anaesthetic, with placement of a Zonular Tension Ring (ZTR), intraocular lens implantation (IOL) and an Iris Prosthetic Implant (IPS) in-the-bag fixation - 4 mms pupil width - Single Element (SE) from Ophtec BV to cover the iris defect. The iris plate implant was matched as much as possible to the iris colour with the available 3 colours.

Results:

Following a successful surgical procedure with the iris plate implant, Mr AS was extremely pleased and reported complete resolution of the double vision. His glare had completely disappeared and his visual acuity improved to 6/6. The intraocular pressure was normal and the eye settled very well.

Conclusions:

Elements from the Iris Prosthetic System are extremely valuable as a surgical device to cover iris defects. In our patient, contact lenses were tried but not tolerated. Corneal tattooing was also offered but declined. The iris defect was too large for suturing and would also have resulted in distortion of the iris and possible inflammation from iris manipulation. All symptoms relating to the iris defect were successfully eliminated using the IPS SE implant. FINANCIAL INTEREST: NONE
