This chapter includes corneal surgeries performed in the center such as corneal transplantation (PK, DALK, DSAEK, DMEK) with all possible complications: graft rejections, recurrence of previous diseases, reactivation of previous infection, and other rare complications. Photos of conjunctival limbal autotransplantation, Boston type 1 keratoprosthesis surgery, and corneal tattooing are included as well. Some interesting cases are discussed with management. Several possible complications after excimer laser procedures are also presented.

The Mean

Corneal transplant surgery after chemical or thermal burns has a very low success rate. Vision in these patients can be restored by using an artificial cornea (keratoprosthesis). In this report, we present 5 clinical cases of implanting a fresh corneal graft with Boston type 1 keratoprosthesis in patients with corneas inappropriate for standard corneal transplantation. The mean follow-up was 26.4 months (range, 12 to 36 months; SD, 13.1). The main measures of outcomes were visual acuity and keratoprosthesis stability. At least 1 year after the operation (5 eyes), vision acuity was >0.1 in 100% of the eyes and >0.4 in 50% of the eyes. Retention of the initial keratoprosthesis was 100%. The results of this study seem to be similar to those reported internationally. The anatomical and visual functions of the eyes were stable after keratoprosthesis implantation, though for a longer follow-up period, additional surgical procedures may be required.

Retroprosthetic Membrane

Background/aimsTo evaluate the time needed for patients with Boston type 1 keratoprosthesis (KPro) to reach their best-corrected visual acuity (BCVA) and all contributing factors.MethodsWe retrospectively reviewed 137 consecutive eyes from 118 patients, measured how long they needed to reach their BCVA and looked at factors that might affect this time duration including patient demographics, ocular comorbidities and postoperative complications.ResultsThe mean follow-up was 5.49 years. The median time to BCVA postoperatively was 6 months, with 47% of patients achieving their BCVA by 3 months. The mean best achieved logMAR visual acuity was 0.71, representing a gain of 6 lines on the Snellen visual acuity chart. Postoperative glaucoma, retroprosthetic membrane (RPM) and endophthalmitis prolonged this duration. We found no correlation between the following factors and time to BCVA: gender, age, indication for KPro surgery, primary versus secondary KPro, number of previous penetrating keratoplasties, previous retinal surgery, intraoperative anterior vitrectomy and preoperative glaucoma.ConclusionIn our retrospective cohort, the majority of subjects reached their BCVA between 3 and 6 months after KPro implantation. This duration was significantly prolonged by the development of postoperative glaucoma, RPM and endophthalmitis.
