Brief Summary
The purpose of this study is to compare the Ziemer Ophthalmic Systems AG GALILEI G6 Lens Professional to the Oculus Pentacam® AXL for taking images and measurements of the anterior segment of the eye, including the cornea, pupil, anterior chamber and lens, to assist in determining the power of the intraocular lens for implantation.

Study Arms (2)
GALILEI G6 Lens Professional
EXPERIMENTALThe GALILEI G6 Lens Professional will measure anterior segment geometry and axial intra-ocular distances of the eye.
Oculus Pentacam AXL
ACTIVE COMPARATORThe Oculus Pentacam AXL will measure anterior segment geometry and axial intra-ocular distances of the eye.
Interventions
Eight measurements of the eye using the GALILEI G6 Lens Professional will be taken using two different devices and 2 different operators
A single measurement of the eye will be taken using the Oculus Pentacam AXL
Eligibility Criteria
You may qualify if:
- Satisfies one of the subject group categories and the enrollment quota for that category has not been reached:
- Normal eyes (phakic eyes without cataracts or corneal disease, refraction ≥ -5.5 D or ≤ +5.0 D)
- Eyes having undergone previous refractive surgery (LASIK or PRK)
- Eyes with cataracts (LOCS III grading with grades 2-6 in any or all of the posterior subcapsular (P2-P5), nuclear (N2-N5) and cortical (C2-C5), assessed by slit lamp examination; no other known ocular pathology)
- Eyes with severe myopia (≤ -6 D according to the American Academy of Ophthalmology)
- Eyes with severe hyperopia (≥ +5.25 D according to the American Academy of Ophthalmology)
- Eyes with previous cross-linking and eyes with advanced keratoconus
- Manifest refraction sSpherical eEquivalent Refraction (MRSER) between -10dpt and +10dpt as measured by cycloplegic autorefraction assessed less than 12 months prior to enrollment
- Best corrected visual acuity (BCVA) of LogMAR 0.2 or better
You may not qualify if:
- Strabismus, nystagmus, amblyopia, anisometropia (difference in MRSER\>3D)
- Angle closure glaucoma
- Seizure disorder, brain damage, Down Syndrome, Trisomy 13 or 18, Cerebral Palsy or other serious ophthalmic or central nervous system disorders
- Severe dry eye
- Severe corneal scarring
- Inability to hold gaze
- Inability to see fixation target
