HI (holographic interferometry) (dx)

HI (holographic interferometry) (dx)

evaluates corneal damage after refractive sx

curvature

damage

asphericity

Argon

He-Ne

Krypton

(so only (some) gas lasers)

SLO (scanning laser opthalmoscope) (dx)

optomap

microperimetry

determine retinal spot with best VA

Argon

Diode semi-conductor

LVD (laser doppler velocimetry) (dx)

measure blood flow velocity

He-Ne

Diode semi-conductor

RLP (retinal laser polarimetry) (dx)

assess the retinal nerve fiber layer (RNFL) thickness and to detect changes associated with various eye conditions, particularly glaucoma

LI (laser interferometry) (dx)

measure the axial length of the eye, corneal curvature, and anterior chamber depth, which are essential for determining the suitability of patients for refractive surgery such as LASIK

PRK (photorefractive keratectomy) (cornea)

reshape cornea

epithelium is removed then treated

excimer

Er: YAG Erbium

LASIK (cornea)

reshapes the eye by creating a thin flap on the cornea

excimer

LASEK (cornea)

epithelium is weakened with an alcohol

excimer

PTK (photorefractive keatectomy) (cornea)

corneal issues such as scars, irregularities and dystrophies

excimer

Nd: YAG Neodymium

PRP (panretinal photocoagulation) (retina)

retinal conditions such as diabetic retinopathy & retinal vein occlusion
