Clinical Trial Summary

The main objectives of this feasibility study were:

• To demonstrate the feasibility of HARMONI Modular Intraocular Lens (HMIOL) implantation and assembly in subjects undergoing cataract surgery (All HMIOL Cohort), and

• To demonstrate the feasibility of the HMIOL optic component exchange procedure (performed 3 months following primary cataract extraction) (Cohort 2).

Description:

Eligible subjects with bilateral cataracts underwent cataract extraction and IOL implantation using phacoemulsification. The study eye was implanted with the investigational device (All HMIOL Cohort). The fellow eye was treated with a commercially available intraocular lens (IOL) per standard of care procedure. At the scheduled Month 3 post-operative visit, subjects who did not opt to pursue an optic exchange procedure in the study eye were enrolled into subgroup Cohort 1 and followed for an additional 6 months. The total duration of participation for Cohort 1 was up to 15 months, which included a Day -90 to Day -1 preoperative period and a 12 month post-operative follow-up period. At the scheduled Month 3 post-operative visit, subjects who elected to pursue an optic exchange procedure in the study eye were enrolled into subgroup Cohort 2 and followed for an additional 12 months. The total duration of participation for Cohort 2 was up to 18 months, which included a Day -90 to Day -1 preoperative period, an optic exchange at Month 3 postoperative, and a 12 month post-exchange follow-up period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Eyes With Postoperative BCDVA 20/40 Snellen or Better by Study Visit - All HMIOL Cohort	Visual acuity (VA) was assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS)-Fast method under well-lit conditions at a distance of 4 meters (m) with the correction obtained from manifest refraction testing. BCDVA was recorded in Snellen, with 20/20 considered to be 'normal' vision. A visual acuity of 20/40 means the participant is able to read a certain size letter 20 feet away that a person with 'normal' vision would be able to read from 40 feet away. This analysis was prespecified for the study eye. No formal statistical hypothesis testing was planned.	Month 1 postoperative, Month 3 postoperative
