Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects with visually significant bilateral cataracts (cortical, nuclear, posterior subcapsular, or a combination) were implanted unilaterally (in one eye only) or bilaterally (in both eyes) with the HMTIOL. A total of 7 study visits were planned, including a preoperative visit, operative visits for each eye, and 4 follow-up visits at 1 day, 1 week, 1 month, and 3 months postoperative. The total duration of participation for each subject was up to 6 months, including the preoperative period (up to 3 months).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Planned removal of visually significant bilateral cataract by manual phacoemulsification cataract extraction
* Pre-existing corneal astigmatism in at least 1 eye of 0.75 to 2.50 diopter (D)
* Target dioptric lens power within the range of 16 - 26 D
* Willing to discontinue contact lens wear for the duration of the study
* BCVA projected to be ≤0.2 logarithm minimum angle of resolution (LogMAR)
* Stable cornea
* Dilated pupil size at least 7.0 millimeters (mm)
* Able to understand and provide informed consent.

Exclusion Criteria

* History of any intraocular or corneal surgery in study eye (including refractive)
* Pregnant or lactating
* History of any clinically significant retinal pathology or ocular diagnosis in study eye that could alter or limit final postoperative visual prognosis
* History of ocular conditions which could affect the stability of the IOL in study eye
* Any anterior segment pathology likely to increase the risk of complications from phacoemulsification cataract extraction in study eye
* Any visually significant intraocular media opacity other than cataract in study eye
* Uncontrolled glaucoma in study eye
* Uncontrolled systemic disease
* Severe dry eye that would impair the ability to obtain reliable study measurements
* Systemic medication that may confound the outcome or increase the intraoperative and postoperative risk to the subject.
