Single Center Exploratory Study To Evaluate The Use Of The RxSight Light Adjustable Lens (LAL) And The Light Delivery Device (LDD) To Improve Visual Outcomes

Completed

Brief Summary: The objective of this study is to evaluate, for the visual correction of aphakia, whether the RxSight Light Adjustable Lens (LAL) and Light Delivery Device (LDD) can be used to improve visual outcomes after performing adjustments of the LAL with the LDD. This is an exploratory study. No primary effectiveness endpoints will be identified.

Recruitment & Eligibility

Inclusion Criteria

Must sign a written Informed Consent form and be willing to undergo cataract surgery for unilateral or bilateral implantation of the RxLAL.
Age 30 or older on the day the cataract surgery is performed.
Study eye must have cataract causing reduction in best corrected distance visual acuity (BCDVA) to a level of 20/32 or worse with or without a glare source.
Willing and able to comply with the requirements for study specific procedures and visits.

Exclusion Criteria

Study eye with zonular laxity or dehiscence.
Study eye with diabetes with any evidence of retinopathy.
Study eye with history of uveitis.
Subjects taking systemic medication that may increase sensitivity to UV light such as tetracycline, doxycycline, psoralens, amiodarone, phenothiazines, chloroquine, hydrochlorothiazide, hypericin, ketoprofen, piroxicam, lomefloxacin, and methoxsalen. LDD treatment in patients taking such medications may lead to irreversible phototoxic damage to the eye. This is only a partial list of photosensitizing medications. Please evaluate all medications that the patient is taking for this effect prior to consideration for implantation.
Subjects taking a systemic medication that is considered toxic to the retina such as tamoxifen.
Study eye with history of ocular herpes simplex virus.

Primary Outcome Measures

Name	Time	Method
Proportion of Eyes Simultaneously With (1) Monocular UCDVA of 20/25 or Better and (2) Monocular Uncorrected Intermediate Visual Acuity (UCIVA) of 20/32 or Better and (3) Monocular Uncorrected Near Visual Acuity (UCNVA) of 20/40 or Better	12 months post op	Visual performance parameters will be collected and summarized for eyes that received a presbyopia adjustment
Percent of Eyes With Uncorrected Distance Visual Acuity (UCDVA) of 20/20 or Better	3 months post op	Values were measured via Early Treatment Diabetic Retinopathy Study (ETDRS) testing.
