ABSTRACT Purpose To report a case of double descemet membrane forming a double anterior chamber following ‘Big bubble’ DALK converted to PKP. Results A 52-year-old man with keratoconus underwent DALK operation converted to PKP due to macro perforation of the descemet membrane. On the postoperative evaluation a remnant of the host's descemet membrane formed a double anterior chamber. After a few months with no intervention, an attempt to deflect a thickened descemet membrane had failed, making entrance into the anterior chamber in order to excise the membrane inevitable. Two years following the second surgery a graft endothelial failure and cataract formation was documented, leading to a second corneal transplantation and lens implantation. Conclusion Double DM is an unusual condition following a DALK procedure which was converted into PKP. In the above case this complication resulted in multiple procedures and graft failure. We believe that early interventions such as gas injection or YAG laser could have resulted in a more favorable outcome. How to cite this article Graffi S, Naftali M.

Corneal Graft Failure

Tube shunts can be placed in the anterior chamber, the ciliary sulcus, or the pars plana. However, if the eye is phakic, the choice is limited to the anterior chamber; ciliary sulcus placement is likely to result in cataract formation, and pars plana placement will likely complicate removal of the cataract that will likely develop. Most corneal complications of tube shunt surgery result from tubes that are too anterior. Loss of vision may result due to these complications. If the tube is inadvertently inserted too close to the cornea, a loss of endothelial cells will result in edema and require transplantation to restore vision. Reported rates of corneal complications range from 2% to 33% and consist mostly of corneal edema/decompensation and corneal graft failure. In a cohort of patients implanted with the Ahmed™ Glaucoma Valve (New World Medical, Inc., Rancho Cucamonga, California), postoperative corneal abrasions occurred in 5 of 60 (8%) eyes. Another study reported the rate of corneal drying/dellen later in the postoperative course (8 of 59 eyes; 13.6%). Contact between the tube and the cornea has been noted at a rate of up to 5%. As the rate of tube shunt implantation has increased, the incidence of corneal edema in patients with tube shunts has also increased. Some of these cases develop corneal opacification with decreased vision and may require corneal transplantation to clear the visual axis. One large study of patients with Ahmed tube shunts (159 eyes total) reported corneal graft failure resulting in repeat penetrating keratoplasty (PKP) in 11 of 31 (35%) eyes with corneal grafts. Improper anterior chamber tube entry may damage the cornea. If the entry angle is not parallel to the iris and aims anteriorly, the needle used to create the tunnel may tear or detach Descemet’s membrane. Entry through the cornea (rather than the sclera) may also predispose to epithelial downgrowth or tube extrusion. To avoid such a complication, fullthickness entry into the anterior chamber should be as far posterior as possible.

We describe a case of Urrets-Zavalia syndrome (UZS) in a healthy 56-year-old woman who underwent femtosecond-assisted phacoemulsification with intraocular lens implantation in both eyes. One month after an uneventful postoperative course in the left eye, the right eye was operated. Dilated pupil which was nonreactive to light appeared on day 21 postoperatively. This was discovered upon examination following anterior chamber inflammatory reaction which occurred 2 weeks following her surgery. Our case report emphasizes the importance and danger in developing UZS even if the reaction in the anterior chamber does not occur immediately after surgery. In addition, the importance of intraocular pressure follow-up in the period after UZS is acknowledged.
