Abstract: Purpose: To assess the efficacy of photorefractive keratectomy (PRK) in patients who underwent corneal transplantation, and to determine the influencing factors. Methods: The present study was a retrospective chart review research that was conducted at Dhahran Eye Specialist Hospital between 2014 and 2017. Results: Seventy-nine eyes were included in the study. The mean BCVA showed an improvement of two lines post-PRK as compared to that before PRK (0.73 ± 0.1 and 0.54 ± 0.2, respectively). There was a statistically significant decrease in the cylindrical value postoperatively as compared to that preoperatively (−2.15 ± 1.4 and−3.25 ± 1.8, respectively; p < 0.001). However, there was no statistically significant difference in spherical equivalent and sphere. Three eyes (4%) developed postoperative complications. There was a medium positive correlation between residual stroma and achieved spherical equivalent (SE) (r = 0.305, p = 0.006), as well as between optical zone and postoperative uncorrected visual acuity (r = 0.350, p = 0.001), in addition to post SE (r = 0.307, p = 0.006). However, the depth of ablation showed a medium negative correlation with achieved SE (r = −0.375, p = 0.001). Conclusion: PRK may be an option for correcting refractive errors in patients who underwent keratoplasty. The optical zone and residual stromal thickness have a positive correlation with the effects of the outcomes, whereas the depth of ablation has a negative correlation with the outcomes.

Abstract: Background: Dupuytren’s contracture is a fibroproliferative disorder that often results in contractions of the fourth and fifth digits of the hand. While there is no definitive cure, symptomatic relief can be achieved via open fasciotomy, percutaneous aponeurotomy, or through collagenase Clostridium Histolyticum injections (CCH). Despite these therapeutic options, the insurance coverage of these modalities is not clearly defined. Methods: The authors evaluated American insurance companies’ coverage for the treatment of Dupuytren’s and compared the coverage of open fasciotomy, percutaneous aponeurotomy, or CCH. A cross-sectional analysis of US insurance policies for coverage of Dupuytren’s treatment was performed. Companies were selected based on those with the largest enrollment and their market share. Results: Of the 100 companies examined, only 5% of companies had an established policy that covered an open fasciotomy treatment, 6% had a policy that covered a percutaneous fasciotomy, whereas 37% had a policy for CCH. There were significantly more policies for CCH compared to open fasciotomy and percutaneous fasciotomy (CCH vs open fasciotomy: p<0.001; CCH vs percutaneous fasciotomy: p<0.001). The most common criterion for treatment options was the involvement of the MP joint or PIP (Open fasciotomy n = 5 (100%); percutaneous fasciotomy n = 5 (83.3%); CCH n = 30 (81.1%). Conclusion: There are noted coverage discrepancies between companies for the coverage of Dupuytren’s management. This variability is overall lacking in surgical, minimally invasive, and injection options.
