Study summary

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.

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. Corrected 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

Secondary outcomes

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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

  6. Anterior Chamber Depth

    Anterior chamber depth will be measured using IOLMaster 500 and Pentacam.

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  7. Pupil Size

    Pupil diameter will be measured using IOLMaster 500 and Pentacam.

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  8. Central Corneal Thickness

    Central corneal thickness will be measured using Pentacam.

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  9. Anterior Chamber Angle

    Anterior chamber angle will be measured using Pentacam.

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  10. Primary and Secondary Spherical Aberrations

    Primary and secondary spherical aberrations will be measured using Pentacam.

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  11. Patient-Reported Spectacle Independence

    Degree of spectacle independence will be assessed using the Patient-Reported Spectacle Independence Questionnaire (PRSIQ).

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery

  12. Patient-Reported Quality of Vision

    Quality of vision will be assessed using the Quality of Vision Questionnaire (QoV).

    Time frame: Measured at the follow-up visit up to 60 months after cataract surgery
