Purpose: To evaluate the visual performance after bilateral implantation of a toric diffractive aspheric multifocal intraocular lens (IOL) with a +2.17 diopters (D) (60 cm) intermediate and a +3.25 D (40 cm) addition (add) power.
Methods: This prospective single-arm study was conducted at the Department of Ophthalmology, Goethe University, Frankfurt, Germany. Twenty-five patients (50 eyes) received bilateral implantation of the toric PanOptix IOL (AcrySof IQ PanOptix; Alcon Research LLC) before enrollment. Exclusion criteria were previous ocular surgeries excluding lens surgery and ocular pathologies or corneal abnormalities. Examination at 3 months postoperatively included manifest refraction; monocular and binocular uncorrected distance (UDVA) and distance-corrected (DCVA) visual acuity at 4 m and 80, 60, and 40 cm; and slit-lamp examination. At 3 months postoperatively, monocular and binocular defocus, binocular contrast sensitivity under photopic and mesopic conditions, and optical phenomena, and spectacle independence were evaluated.
Results: Mean refractive spherical equivalent was 0.12 ± 0.380 D and mean refractive cylinder was -0.21 ± 0.237 D at 3 months postoperatively. A significant decrease in refractive cylinder was observed postoperatively (P < .05), with 98% showing a postoperative astigmatism below 0.75 D. Monocular UDVA was better than 0.14 logMAR in all distances. Binocular defocus curve showed peaks at 0.00 D (-0.09 logMAR) and -1.50 and -2.00 D (-0.02 and 0.00 logMAR). The worst values between far (4 m) and near (40 cm) distance were 0.04 logMAR at -1.00 D. Despite some optical phenomena, 92% of patients would choose the same IOL again and recommend it to others.
Conclusions: The visual performance of the toric PanOptix IOL showed good visual acuity at all distances; more than 90% achieved a decrease of refractive cylinder below 0.75 D, high patient satisfaction despite some optical phenomena, and high spectacle independence 3 months postoperatively.

To evaluate the safety and efficacy of the Saroa Surgical Robot System in robot-assisted laparoscopic radical prostatectomy (RARP). We enrolled 60 patients who underwent RARP using either the Saroa (n = 9) or da Vinci Xi (n = 51) systems at Jikei University Kashiwa Hospital from January 2022 to March 2024. We compared preoperative characteristics, perioperative outcomes, complications, and postoperative urinary continence at three months between the two groups.

Anastomotic dehiscence (AD) remains a significant postoperative complication, and anastomoses are typically created using either manual suturing or mechanical stapling, each with specific benefits and challenge. Material and this retrospective study analyzed outcomes in 100 rectal cancer patients who underwent surgical resection, with anastomoses performed via manual suturing (n=50) or mechanical stapling (n=50).

Background: Patients with or at risk for breast cancer may opt for risk-reducing gynecologic surgeries, including bilateral salpingo-oophorectomies and/or total abdominal hysterectomy. The timing and safety of combining these procedures with autologous breast reconstruction (ABR) are debated. This study assesses the impact of concurrent ABR and gynecologic surgeries on clinical and patient-reported outcomes.

Background: Frailty screening instruments are increasingly studied as risk predictors for adverse postoperative outcomes. However, because of the lack of comparative research, it is unclear which screening instrument performs best. This study therefore compared the diagnostic accuracy of seven frailty screening instruments for adverse postoperative outcomes in patients aged ≥70 years undergoing colorectal surgery.

Department of Neurosurgery, The Affiliated Hospital of Jiangsu University, Zhenjiang, China.
Background: Surgery for tumors in the cerebellopontine angle is always a significant challenge due to the densely packed neurovascular structures, the narrow deep location, and the complex relationship between the lesions and surrounding neurovascular structures. Recently, great attention has been given to the neuroendoscope for its exclusive advantages, which have added a new dimension to many classical microscopic surgeries. However, the feasibility and advisability of fully endoscopic neurosurgery for cerebellopontine angle tumors remain to be further evaluated.
