Safety and Efficacy Study to Evaluate the Treatment of Both Near and Distance Vision in a Simultaneous Laser Procedure

Inclusion Criteria: * Subjects must be at least 45 years old and not older than 85 years * 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 be willing to have both eyes treated with the laser during the same visit. * Subjects for study arm-I must have up to +4 diopters (D) of absolute spherical hyperopia (not spherical equivalent), with up to +2.5 D of refractive astigmatism (NOT corneal astigmatism) by manifest subjective refraction in both eyes. The spherical equivalent must be no more than +5.25 D. Subjects for study arm-II must have up to -7 diopters (D) of absolute spherical myopia (not spherical equivalent), with up to -4.0 D of refractive astigmatism (NOT corneal astigmatism) by manifest subjective refraction in both eyes. The spherical equivalent must be no more than -9.00 D. * Subjects must have presbyopia as determined by an age-related need for optical aid (\> +1.50 D) for reading with their best distance correction. * Subjects who have been screened successfully for acceptance of the PresbyLasik simulation * Subjects who are contact lens wearers must have gas permeable (GP) lenses discontinued for at least 3 weeks and soft lenses discontinued for at least 1 week prior to the preoperative evaluation in the eye to be treated. Contact lens wearers who wear their contact lenses for any amount of time between the preoperative baseline examination and the operative visit must not be treated. * Corneal topography should be normal. * Subjects who are contact lens wearers must have 2 central keratometry readings and 2 manifest subjective refractions taken preoperatively at least one week apart. The refraction values must not differ by more than 0.50D as defined by manifest refraction spherical equivalent (MRSE). The keratometry values must not differ from the previous values by more than 0.50D in either meridian. * High contrast, manifest, best spectacle-corrected logMAR distance visual acuity (VA) must be correctable to at least 0.1 (20/25 or 6/7.5) in both eyes. 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 posterior corneal thickness below the flap postoperatively. * Eyes for which the baseline manifest subjective refraction exhibits a difference of greater than 0.75D in sphere power, or a difference of greater than 0.50D in cylinder power, or a difference in cylinder axis of more than 15 degrees compared to the baseline cycloplegic subjective refraction. For manifest cylinder of less than 0.75D, the difference in cylinder axis will not be taken into consideration. * 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. * Any subject who is going to be co-managed by an ophthalmologist or optometrist who is not approved as a Technolas Perfect Vision GmbH Excimer laser Investigator. * Subjects with anterior segment pathology, including dry eye syndrome and cataracts which in the Investigator's opinion, would interfere with best spectacle-corrected VA (BSCVA) or a successful treatment. * Subjects with evidence of retinal vascular disease. * Subjects with any residual, recurrent, or active ocular disease, or corneal abnormality that in the Investigator's opinion would interfere with BSCVA or a successful treatment. * Subjects with signs of keratoconus. * Subjects with unstable central keratometry readings with irregular mires. * Subjects who have undergone previous intraocular or corneal surgery of any kind, including any type of excimer laser surgery for either refractive or therapeutic purposes. * Subjects who have a history of Herpes simplex or Herpes zoster keratitis. * Subjects who have a history of glaucoma or glaucoma suspect. * Subjects who are immunocompromised or carrying diagnosis of connective tissue disease, clinically significant atopic disease, diabetes, autoimmune diseases and other acute or chronic illnesses that will increase the risk to the subject or confound the outcomes of this study. * Subjects taking systemic medications likely to affect wound healing such as corticosteroids or antimetabolites. * Subjects who are known to be pregnant, lactating, or who plan to become pregnant during the course of the study. * Subjects with known sensitivity to medications used for standard LASIK. * Subjects participating in any other ophthalmic clinical trials during this clinical trial. * Subjects with an ocular muscle disorder including a strabismus or nystagmus, or other disorders affecting fixation. * Subjects at risk for angle closure.
