The aim of the study is to create a patient registry that will allow for comparison of cataract treatment outcomes using phacoemulsification with implantation of different types of intraocular lenses.
This study will establish a registry to evaluate outcomes associated with intraocular lens implants in patients undergoing cataract surgery. Retrospective assessments will include routinely collected preoperative, intraoperative, and postoperative data. Prospectively, visual acuity, refraction, examination findings, patient-reported outcomes, and complications will be collected for up to 60 months after surgery.
Study Type
OBSERVATIONAL
Enrollment
300
Implantation of an intraocular lens following phacoemulsification cataract extraction, with lens type selected according to routine clinical practice (e.g., monofocal, toric, multifocal, or extended-depth-of-focus).
Sensor Cliniq
Warsaw, Poland
RECRUITINGCorrected and Uncorrected Distance, Intermediate and Near Visual Acuity
Distance, intermediate, and near visual acuity will be measured both uncorrected and corrected using standard ETDRS charts at 4 meters for distance, 66 cm for intermediate, and 40 cm for near visual acuity.
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
Objective Refraction
Spherical and cylindrical refractive errors will be measured objectively using an autorefractometer.
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
Subjective Refraction
Spherical and cylindrical refractive errors will be measured subjectively using trial frame glasses and patient responses.
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
Monocular and Binocular Defocus Curve
Visual acuity will be measured at varying defocus levels under monocular and binocular conditions to assess the range of functional vision. Measurements will be taken in 0.5 D steps from +1.00 D to -2.50 D.
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
Contrast Sensitivity
Contrast sensitivity will be assessed using the Matrix Perceptix test under photopic light conditions.
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
Keratometry
Keratometry will be measured using IOLMaster 500 and Pentacam
Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
