Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 21 and older with cataract grade 1 or higher in at least one eye.
✕Probably not a fit
Patients with active ocular infections, significant eye movement abnormalities, or contraindications for pupil dilation may not benefit from this study.

What this trial studies
This study evaluates and compares the refractive outcomes of cataract surgery using two different optical biometers: the Argos 1.5 and the IOLMaster 700. Both devices are standard in surgical planning for cataract extraction, and the study aims to determine which device provides more accurate intraocular lens (IOL) power calculations. Accurate measurement of ocular parameters is crucial for achieving optimal postoperative visual outcomes. The study will include adults with cataracts and assess their potential for achieving emmetropic vision post-surgery.
Why it matters
Potential benefit: If successful, this study could enhance the accuracy of IOL power calculations, leading to improved visual outcomes for cataract surgery patients.
How similar studies have gone: Previous studies have shown success with similar biometry approaches, indicating potential for meaningful advancements in cataract surgery outcomes.

Show full inclusion / exclusion criteria
Inclusion Criteria: * 21 years or older (Adult age) * Assessed to have Cataract Grade 1 and above per LOCS III or Wisconsin Grading scale in at least one eye. * Able to comprehend and sign the informed consent form. * Potential postoperative best corrected distance visual acuity (BCDVA) of 0.3 logMAR or better and targeted post-op refraction to be emmetropia, based on the investigator expert medical opinion. Exclusion Criteria: * No active ocular infection or inflammation * Unable to fixate due to nystagmus or other eye movement abnormality (e.g., significant strabismus) * Contraindicated for pupil dilation (e.g., narrow angles, allergies) per medical judgement of the investigator. * Any ocular disease and/or condition that, in the investigator's clinical judgment, may put the subject at significant risk, may compromise study result or may interfere significantly with the subject's participation in the study.
