To determine whether the rate of graft detachment in patients undergoing the DSAEK procedure is influenced by the time elapsed between donor death and tissue implantation. Methods. Data on procedure outcome and donor tissue for patients undergoing the DSAEK procedure were reviewed. Data on time elapsed between harvest, processing, storage, and implantation of the tissue, as well as donor tissue endothelial cell count were obtained from reports made available from the Eye Bank of Canada. The adverse outcome of interest was graft detachment. Results. 71 cases were reviewed, with 14% resulting in detachment. The following time periods were compared between detachment and nondetachment groups: donor death to enucleation; enucleation to processing; duration of storage at the Eye Bank to implantation. No statistically significant differences were found (Student's t-test, P > 0.05). Endothelial cell counts of donor tissue were compared between the two groups, and no statistically significant difference was found (Student's t-test, P > 0.05). Conclusion. The range of processing times and endothelial cell counts in donor tissue available from the Eye Bank did not predict a change in the rate of graft dislocation in one surgeon's practice.

To observe and classify vitreous incarcerations in patients undergoing second 20-gauge pars plana vitrectomy (PPV) for recurrent retinal detachment. Methods. Retrospective noncomparative consecutive case series. Eighty-two consecutive patients with recurrent retinal detachment were included. The previous sclerotomy sites were examined by our sclera depression method and the vitreous incarceration were classified into Grade 0-IV by their severity under surgical microscope before second surgery. The relationship of vitreous incarceration and different ports was statistically investigated in our included patients. Results. Vitreous incarceration in the previous sclerotomy sites were found frequently. Vitreous cutter sites were most involved, but the infusion pipe sites were the least. According to our classification and definition, Grade III and IV of vitreous incarceration in all the three different sclerotomy sites accounted for 32.5%. Grade II of vitreous incarceration consisted of 12.6%. Grade 0 and I in all the three different sclerotomy sites were 54.8%. The frequency of all grades of vitreous incarceration in light port or vitreous cutter port was significant higher than that in infusion port. Conclusions. Vitreous incarceration in light port and vitreous cutter port are found more common than in infusion port for 20-gauge PPV with our new method.

To report outcomes of graft refractive surgery (GRS) along with clear-cornea phacoemulsification and intraocular lens (IOL) implantation in penetrating keratoplasty (PKP) eyes. Methods. Fourteen eyes of 13 patients who had received PKP underwent simultaneous GRS (relaxing incisions with or without counter-quadrant compression sutures) and clear-cornea phacoemulsification with IOL implantation. To calculate IOL power, preoperative keratometry readings and the SRK-T formula were used. Results. Mean patient age and follow-up period were 50.5 ± 14.4 years and 14.6 ± 7.1 months, respectively. A significant increase was observed in best spectacle-corrected visual acuity (from 0.55 ± 0.18 logMAR to 0.33 ± 0.18 logMAR, P = 0.001). There was a significant decrease in vector keratometric astigmatism by 6.22 D (P = 0.03). Spherical equivalent refraction was reduced from -3.31 ± 3.96 D to -1.69 ± 2.38 D (P = 0.02) which did not significantly differ from the target refraction (-0.76 ± 0.14 D, P = 0.20). No complications developed and all the grafts remained clear at the final examination. Conclusion. Simultaneous phacoemulsification and GRS is a safe and effective method to address post-PKP astigmatism and lens opacity. IOL power can be calculated from preoperative keratometry readings with an acceptable accuracy. However, patients should be informed about the possibility of high refractive errors postoperatively.

A total of seventy (n = 70) subjects consisting of 31 males and 39 females participated in this study. Subjects were categorized into emmetropia, hyperopia and myopia using the spherical equivalent refraction. The axial length was measured with I-2100 A-Scan ultrasonography/Biometer (CIMA Technology, USA), the corneal radius of curvature with Bausch & Lomb H-135A (Bausch & Lomb Corp., USA), and the refractive state by static retinoscopy and subjective refraction. The mean AL, CRC and AL/CRC ratio of all subjects were 23.74 ± 0.70 mm, 7.84 ± 0.19 mm, and 3.03 ± 0.14, respectively. Myopes had significantly longer AL, steeper CRC and higher AL/CRC ratio than the emmetropes and hyperopes. There was statistically significant inverse correlation between AL and CRC (r = -0.53, P < 0.0001), SER (r = -0.64, P < 0.0001), and between SER and AL/CRC (r = -0.78, P < 0.0001). A significant positive correlation was found between CRC and SER (r = -0.69, P < 0.0001). The categorization of the refractive state of an individual is better done by using the AL/CRC ratio index.
