Interventions

Nidek Tonoref IIIdevice

The auto ref/kerato/tono/pachymeter TONOREF III is a medical device which measures objective refractive errors, corneal curvature radius, intraocular pressure and corneal thickness of the patient's eye.

Haag-Streit Goldmann Manual Tonometerdevice

Haag-Streit Goldmann Manual Tonometer measures intraocular pressure to aid in the screening and diagnosis of glaucoma

NIDEK CEM-530device

Nidek CEM-530 is a non-contact ophthalmic microscope, optical pachymeter, and camera used for examination of the corneal endothelium and for measurement of the thickness of the cornea.
