The device employs a generic femtosecond laser used in numerous other ophthalmic procedures.

The refractive correction is effected through the treatment, which is employed at least 30 days after cataract surgery.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
