![]() AS-OCT was performed on the first postop day. The intended incision width was 2.85 mm and length was 1.8 mm. The first plane was at 90 degrees to the corneal surface and extended to 40 percent corneal depth, the second was an angled intrastromal plane and the third plane was at 45 degrees to the posterior corneal surface and reached the second plane at 70-percent depth. Of these 18 patients with IFIS and more than one intraoperative complication, 27.8 percent (five of 18) had pupillary expansion devices used.Īn intended triplanar incision was programmed into the Catalys. Thirty-eight patients with IFIS had at least one intraoperative complication, and 18 patients with IFIS had more than one intraoperative complication ( p<0.00001). Of patients with posterior capsule tear, 88.2 percent (15/17) had vitreous prolapse that required vitrectomy only four of these involved the use of a pupillary expansion device (23.5 percent). Seventeen patients had anterior or posterior capsule tears (3 percent) five patients had both. However, 75.2 percent of patients with IFIS had taken alpha-blockers preoperatively ( p<0.00001) 430 patients of the total studied (8.7 percent) had a pupillary expansion device used during their cataract surgery, of which 186 patients had IFIS (43.3 percent, p<0.0001). Of these 1,294 patients, 428 patients (33.1 percent) had documented IFIS. Of 4,923 total cataract surgeries included, 1,294 patients, (26.3 percent) took alpha-blockers preoperatively (selective 627, non-selective 667). None of the patients showed IOP rise or other adverse effects. Only one patient was a steroid hyper-reactor the pressure normalized after the drug was suspended. The change of the mean preop endothelial cell density (2,763.4 cells) to mean postoperative cell density (2,626.9) was statistically significant ( p=0.013). The contrast sensitivity was measured with CDVA, considering the low (6.28 cycles per degree), medium (5.07 cpd) or high (3.78) mean spatial frequencies. The mean postoperative UCVA was 20/30 (logMar 0.17) or better and the BCVA 20/25 (logMar 0.098) or better. The study evaluated 14 eyes of nine patients, age 22 to 53 years, mean 34.1 years 66.6 percent were female mean follow-up was 29 months (r: nine to 38 months). Postoperative whole eye (mean 0.133 µm) and internal SA (mean 0.071 µm) were found to be significantly less than control cases (mean 0.223 µm p<0.001 and mean 0.133 p=0.022 respectively).Ī group in Mexico City assessed the safety and effectiveness of the AcrySof Cachet Phakic angle-supported IOL for the correction of high myopia. Postoperative whole-eye MHOAs (mean 0.484 µm) were found to be significantly less ( p<0.001) than age-matched controls (mean 0.648 µm). The RMS of total internal 3rd ( p<0.001), 4th ( p<0.001), 5th ( p=0.033) and 6th ( p=0.006) orders also showed a significant reduction postoperatively. (See results, below.) There was a significant reduction in total root mean square MHOA following surgery ( p<0.001). Zernike coefficients were obtained to the 6th order. MHOAs were measured over a 5-mm dilated pupil diameter using the iTrace aberrometer. Pre- and postoperative data was compared to 300 eyes of 167 age-matched patients with no visually significant cataract. They measured whole-eye, corneal and internal MHOA before and four weeks after surgery. They conducted a prospective, observational study of 50 patients who underwent uncomplicated cataract extraction to evaluate the effectiveness of an aspheric IOL in reducing monochromatic higher-order aberrations (MHOA). Surgeons in Glasgow, Scotland, report that an aspheric intraocular lens significantly reduces certain higher-order aberrations. ![]()
