Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients were randomized for either combined phacoemulsification and ultrasound ciliary plasty (Phaco-UCP) (the study group) or phacoemulsification alone (the control group). All surgeries were performed by one experienced surgeon (Y EZ).
Preoperative evaluation included manifest refraction, BCVA measurement, slit-lamp biomicroscopy, gonioscopy, indirect ophthalmoscopy, measurement of IOP with Goldmann applanation tonometry (average of 3 readings taken). Corneal diameter (White-to-white) and axial length measurement were done using IOL Master 500 (Carl Zeiss Meditec AG., Germany). Ultrasound pachymetry with Tomey SP-100 (Tomey Corp. Nagoya, Japan) and visual fields using Humphrey Field Analyzer (24-2, SITA, standard program Carl Zeiss Meditec AG., Germany) were also performed.

phaco-UCP
Under peribulbar anesthesia, UCP was performed first, followed by phacoemulsification. UCP was performed using the same technique described before \[18\]. For all treatments, 2nd generation probe was used (EyeOP1, Eye Tech care; France) with the same parameters; Operating frequency was 21 MHz. Number of sectors activated was 6. Acoustic power was 2.45 W; duration of each shot was 8s; and the time between shots was 20s. The probe diameter (11, 12 or 13 mm) was determined according to the eye's biometric readings. The coupling cone was centered on the eye and kept in place with low vacuum suction, followed by introduction of the treatment probe inside the cone, then activation of the transducers by constantly pressing the foot switch. Once UCP treatment was finished, phacoemulsification was commenced

Phaco alone
A standard phacoemulsification was performed with 2.2 mm clear corneal incision, continuous curvilinear capsulorhexis, phacoemulsification and intrabagal implantation of foldable acrylic intraocular lens (AcrySof® IQ SN60WF monofocal; Alcon Laboratories Inc, Fort Worth, TX, USA) for all patients. Irrigation-aspiration was performed for at least 30 seconds to remove any viscoelastic from the anterior chamber. Reformation of the anterior chamber was done with balanced saline solution (BSS), followed by hydration of the corneal wound and side port.
