In patients undergoing major liver resection, the decision to introduce an epidural catheter and the timing of its removal should be made with care because of the prolonged changes in platelet count and in prothrombin time that develop in some patients.

Comparison between treatment with wavefront optimized and custom-Q laser-assisted in situ keratomileusis (LASIK) ablations. Our study included 400 eyes of 200 patients divided into two equal groups. All patients were treated for myopia and myopic astigmatism with LASIK. The first group was treated with wavefront optimized ablation and the second group with custom-Q ablation. They were examined preoperatively and postoperatively to assess asphericity, image quality, and other classical outcome parameters. The wavefront optimized ablation group comprised 200 eyes with a mean spherical equivalent refraction (SE) of -5.2188 diopters (D) (range: -1.15 to -10.50 D); the mean Q-value changed from 0.30 preoperatively to 0.06 postoperatively. The custom-Q ablation group also comprised 200 eyes with a mean SE of -5.1575 D (range: -1.35 to -9.00 D); the mean Q-value changed from 0.32 preoperatively to 0.03 postoperatively. A statistically significant difference in postoperative change in Q-values (P = 0.02) and in postoperative visual acuity (P = 0.42) between the two groups was noted. There was no difference between the two groups regarding refractive correction. There was a marginally significant change in BSCVA (best spectacle-corrected visual acuity) between the two groups, and less impairment in the corneal asphericity in the custom-Q group.

Purpose of the studyTo evaluate efficacy, safety, and success rates of canaloplasty combined with phacoemulsification and intraocular lens implantation in patients with open-angle glaucoma (OAG) and visually significant cataract.Patients and methodsA prospective interventional noncomparative case series carried out in Minia University Hospital from April 2015 to October 2016 on 20 eyes of 18 patients who had visually significant cataract and primary OAG. All the cases had combined phacocanaloplasty. Preoperative best-corrected visual acuity, intraocular pressure (IOP), and number of antiglaucoma medications were collected and compared to postoperative levels, and complications rates were recorded.Results20 eyes of 18 patients (5 males and 15 females), with a mean age 57.6 years (range 48–69 years), underwent phacocanaloplasty. Preoperative mean IOP was 25.20 ±1.009 mmHg. Postoperative IOP decreased to a mean of 14.20±0.9, 14.85±0.8, and 15.85±0.7 mmHG at 3, 6, and 12 months, respectively, with 37% reduction from preoperative IOP level at one year follow-up visit (P=0.0005). The number of antiglaucoma medications dropped from mean of 1.55 preoperatively to 0.35 postoperatively. LogMAR of best-corrected visual acuity improved from 0.6950±0.07 preoperatively to 0.3670±0.056, 0.3460±0.056, and 0.03370±0.052 at 3, 6, and 12 months postoperatively (P=0.0005). Complications were limited to mild hyphemia (one case), mild corneal edema (one case), and mild inflammatory membrane (one case) that resolved in the first week after surgery.ConclusionCanaloplasty combined with clear corneal phacoemulsification and intraocular lens implantation may be a safe and effective procedure to lower IOP in adult patients with OAG and visually significant cataract.

is properly cited.Purpose. To evaluate a new technique of posterior capsulorhexis using air support to treat primary posterior capsular opacification (PCO) during cataract extraction surgery or to prevent postoperative PCO. Setting. Saudi Arabia. Design. Prospective, randomized, consecutive case comparative non controlled study. Methods. One hundred eyes of 100 patients with a mean age of 63.3 years with dense cataract were enrolled in the study. Fifty of them (group (1)) were with primary PCO (discovered during the operations) and fifty (group (2)) with clear posterior capsule. All of the patients underwent phacoemulsification and posterior capsulorhexis using the air to support the posterior capsule. en, IOL implantations were done between the anterior and posterior capsular rims. Postoperatively, each patient was evaluated for the following: visual acuity (UCVA and BCVA), manifest refractive spherical equivalent (MRSE), intraocular pressure, intraocular lens (IOL) stability, visual axis opacification, and posterior segment complications as retinal breaks, retinal detachment, or cystoid macular edema (CME). Results. ere were no significant differences in UCVA, BCVA, and MRSE. All cases had a clear visual axis, with stable IOL and normal IOP during the follow-up period without posterior segment complications. e VA improved significantly throughout the follow-up periods in both groups without significant clinical difference. Conclusion. Pneumatic posterior capsulorhexis is a new effective technique for the treatment of primary PCO in dense cataract and for prevention of postoperative PCO with the good visual outcomes and minimal complications. is trial is registered with NCT04007965.
