Safety and Efficacy of Different Add Powers With a New Presbyopic Lasik Treatment Algorithm

February 29, 2024 updated by: Bausch & Lomb Incorporated

Prospective Clinical Study to Evaluate the Safety and Efficacy of Different Add Powers With a New Presbyopic Lasik Treatment Algorithm

This is a prospective, comparative, randomized, controlled, open-label, single-surgeon, single-center PMCF clinical study whereby presbyopic patients undergoing refractive surgery will receive a SUPRACOR treatment for the correction in the non-dominant eye and a PROSCAN refractive treatment in the dominant eye to correct for ametropia.

The participants will be randomized to either a SUPRACOR regular (100%) or SUPRACOR strong (130%) treatment with a 1:1 ratio.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: SUPRACOR Regular
SUPRACOR algorithm with regular (100%) ablation profile. SUPRACOR is a presbyopic algorithm that consists of a pre-calculated pulse pattern combined to the refractive pattern to combine near, intermediate and distance vision correction.
Experimental: SUPRACOR Strong
SUPRACOR algorithm with strong (130%) ablation profile. SUPRACOR is a presbyopic algorithm that consists of a pre-calculated pulse pattern combined to the refractive pattern to combine near, intermediate and distance vision correction.

This test is performed with best distance corrected refraction and spherical additions ranging from -4.5 D to +1.0 D in 0.5D steps.

Binocular Contrast sensitivity
Time Frame: 3 months follow up
The contrast sensitivity test consists in assessing the possibility to distinguish the alternation of white and grey fringes of difference contrast with difference frequency. Contrast sensitivity will be assessed under photopic and mesopic light conditions using Clinical Trial Suite (M&S Technologies, Niles, IL, USA) device at 2.5 m.

Halo Photic phenomena
Time Frame: 3 months follow up
The amount and disturbance of photic halo side effects will be assessed by two methods: 1) Halo and Glare simulator: With this software tool the particant mimics the individual vision perception by adjusting a typical night scene image with the intensity and size of glare and halo; 2) Siepser Glarometer (Gulden Ophthalmics, Elkins Park, PA 19027). This is a target-like device that measures and quantifies post-operative glare. The measurement is of the participants' actual scope and range of monocular glare and halo.

Patient-Reported Spectacle Independence Questionnaire (PRSIQ)
Time Frame: 3 months follow up
The Patient-Reported Spectacle Independence Questionnaire (PRSIQ) is comprised of 3 questions about the need for glasses or contacts in the past 7 days for distance vision (at least 1.5 meters (m) away), intermediate vision (0.5 m to 1.5 m away), and near vision (< 0.5 m away). Possible scores range from 1 to 5, with 1 = All of the time and 5 = None of the time for six of the questions; 3 of these questions ask the question in a positive way and 3 of the question ask the question in a negative way, so the higher scores are better for the negative question and are worse for the positive question. There are also 3 questions whether glasses or contacts were needed in the past 7 days with scores of Yes = 1 and No = 2. The results for each question will be summarized separately.
3 months follow up
Near Activity Visual Questionnaire (NAVQ)
Time Frame: 3 months follow up
The Near Activity Visual Questionnaire (NAVQ) is comprised of 10 questions about performing activities without extra reading spectacles. Each question has responses of 0 to 4, with 0 indicating 'No difficulty' and 4 indicating 'Extreme difficulty'. Any 'Not applicable' responses are scored according to the median overall score for the subject. The scores are summed with total score ranging from 0 to 30. Higher scores indicate more difficulty performing specified activities without spectacles.
