Description
Inclusion Criteria:
- Subjects must be at least 45 years old
- Subjects must read, understand, and sign an Informed Consent Form (ICF).
- Subjects must be willing and able to return for scheduled follow-up examinations through 6 months after surgery.
- Subjects must have undergone previous uncomplicated cataract surgery with monofocal IOL implant in the study eye at least 3 months prior to study enrollment.
- Subjects must have up to +/- 2.0 (D) of absolute spherical myopia or hyperopia (not spherical equivalent), with up to +/- 2.0 D of refractive astigmatism (NOT corneal astigmatism) by manifest subjective refraction. The spherical equivalent must be no more than +/- 2.0 D.
- Subjects who have be screened successfully for acceptance of the SUPRACOR simulation
Exclusion Criteria:
- Subjects for whom the combination of their baseline corneal thickness and the planned operative parameters for the LASIK procedure would result in less than 250 microns of remaining corneal thickness below the flap postoperatively.
- Subjects for whom the preoperative assessment of the ocular topography indicates that one or both eyes are not suitable candidates for treatment based upon the suggested computer-simulated treatment plan (e.G. Keratoconus).

Experimental: Supracor
Study arm will consist of patients who have undergone previous cataract surgery with implantation of a monofocal IOL.
The Supracor procedure will be performed on the non-dominant pseudophakic eye of these patients.
|
The presbyopic treatment consists of a standard treatment for distance vision and the procedure known as SUPRACOR addition to correct near vision. The SUPRACOR addition provides a multifocal ablation with a central near addition with an aberration controlled transition zone towards the periphery, thereby allowing good focus over a range of object distances.
