We are reporting the LASIK cases and the results done by two different surgeons. Patients were selected based on a thorough history taking and complete ophthalmologic examination. The variability was decreased by only reporting the cases done by the co-authors since the operative technique followed by the two were virtually similar. Pre-operative corneal topography, videokeratography, and pachymetry were taken together with a thorough routine ophthalmologic history and examination. All patients who were screened were included in the study. The Schwind Microkeratome was used to create the corneal flap, the stromal ablation was then performed using the Schwind Microkeratome-F by Coherent with the Lambda Physik COMPex Excimer Laser. Pre-operative visual acuity was compared from the post-operative results. Likewise, intra-operative and post-operative complications were reported. Regular follow-up was done at 1 day, 1 week, 1 month and 6 months post-op. Visual acuity and refraction were closely monitored during the follow-up. (Author)

Purpose: To compare the efficacy and safety of Proparacaine 0.35%- Fentanyl 0.0015% solution and Lidocaine 2.8% - Fentanyl 0.0015% solution as topical anesthesia for pharmacoemulfification with intraocular lens implantation. Methods: A prospective randomized, triple- masked clinical study. Ninety six patients with senile cataract were divided into two treatment groups Proparacaine - fentanyl group (PF group) and the Lidocaine Fentanyl group (LF group). Volume of anesthetic required latency and duration of anesthesia were compared. Visual analog pain scale was used to assess intraoperative patient's pain. Preoperative patient anxiety; surgeons and anesthesiologists assessment of the operative condition were also determined. Slit-lamp biomicroscopy was done on the first day postoperatively. Unpaired students T- test and descriptive statistics were employed with level of significance at p<0.05. Results: Similar volume of the anesthetics was used in both groups. Mean latency period for the PF solution was 0.51 minutes +/-0.18 (SD) which was significantly shorter than the LF solution at 3.14 minutes +/- 1.09 (p<0.05). Mean duration of anesthetic effect of the PF group was significantly shorter at 33. 47 minutes +/-4.57 while the LF group lasted 69.09 minutes +/- 16.20 9p<0.05). Majority of the patients in both groups [44 (905) PF group; 40 (85%) LF group] denied any pain or discomfort during surgery. Mean pain score was 0.16 PF group and 0.23 for the LF group. The surgeon noted optimal operative conditions while the anesthesiologist reported significant difference in patients response during surgery with hand squeezing noted in 7 (15%) patients in the LF group 9p<0.05%). There was no significant difference in biomicroscopic findings on day 1 postoperatively. Conclusion: Proparacaine 0.035% - fentanyl 0.0015% solution is as effective and as safe as lidocaine 2.8% - fentanyl 0.0015% solution for topical anesthesia in phacoemulsification with intraocular lens implantation.
