Aberrometer is used to measure:: (A) Endothelial count, (B) Keratometry, (C) Higher order abberation, (D) Corneal stroma
Answer is C. Abberrometer is used to measure higher order abberations. Corneal investigations Specular: Endothelial Count. Aberrometer : Corneal higher order abberations. Aesthesiometer: Corneal Sensations. Placido disc: Keratometry(anterior surface of cornea). Pentacam & Orb scan: Both anterior & posterior surface of cornea. Pentacam: Investigative modality of choice to do any corneal topography, it may be keratoconus, ectasia, LASIK. Topography Corneal Topography Confocal microscopy: visualize stroma & used in diagnosis of stromal dystrophies & latent infections.
