Let’s say the spherical power of the eyeglass prescription is -8.00 D. If you look up 8.00 on a standard vertex chart, you’ll see that the corresponding minus power is -7.25D. This patient needs a contact lens power of -7.25D. Since most contacts aren’t available in 0.2...
Contact lensINTACSKeratoconus patientsPurpose: To demonstrate the feasibility of contact lens fitting in keratoconus patients with INTACS inserts.
