Purpose: To investigate the impact of smartphone viewing distance and angle on reaction times.
Design: A prospective, self-controlled, single-center study.
Methods: Participants engaged in a driving simulation facing a large screen with a simulated brake pedal.
Article Synopsis
- The study compares the maximum tensile strength of different 3-piece intraocular lenses (IOLs) used for flanged intrascleral haptic fixation (FISHF) at the Willis-Knight Eye Institute in Louisiana.
- Results showed that the CT Lucia lens had the highest strength (1.53 N), outperforming other lenses like the MA60AC, AR40E, and LAL, with significant differences noted (P < .001).
- The findings suggest that while the strength and angulation of lenses like the CT Lucia may support safe use in FISHF by skilled surgeons, more research is needed to ensure stability under physiological conditions or with light treatments.
The Argentinian flag sign (AFS) is a feared complication during cataract extraction. Intralenticular pressures, especially excessive posterior pressure, have been identified as potential mechanisms for capsular stress and tearing associated with AFS. Capsular tension is created by positive intralenticular pressures, which cause the irido-lens diaphragm to move anteriorly once the manual capsulorhexis has been initiated.

Methods: A single-center, prospective study examined symptomatic patients after bilateral cataract extraction with trifocal IOL implantation. A ten-question survey was conducted one month after surgery.
