Purpose: To present a new method of iridociliary zone tumor removal. Today there is no method of iridocyclectomy without drawbacks such as large number of sutured surfaces, numerous stitches, small residual thickness of superficial flaps, resulting in problems with eyeball sealing, inconvenience of working with the tumor (violation of ablastics rules). We suggest a method eliminating these problems.
Methods: The suggested method includes the following steps. Superficial sclera flap 350 microns thick is formed. The deep flap is formed smaller than the superficial by 0.5mm in length and width (“scleral step”). Entrance to the anterior chamber is performed parallel to the iris surface, after that the deep flap is removed with the part of Schlemm’s canal in the zone of the tumor. Viscoelastic is injected in the anterior chamber to rise the pressure which makes the tumor drop out in the incision. The tumor is excised within healthy tissues beginning from the pupillary edge. Basis of the vitreous remains intact. Iridoplasty is performed to restore the pupillary diaphragm.
Results: 6 patients (6 eyes) were operated with this method. At the first day after surgery visual acuity ranged from 0.3 to 1.0 (mean, 0.74). Intraocular pressure was normal in all cases. Induced astigmatism did not exceed 1.2 D. No complications occurred. Follow-up period was up to 20 month.
Conclusion: The suggested method allows to achieve high anatomic and functional results with low complication rate.
