Procedures

Laser Peripheral Iridotomy- LPI

This laser is done for narrow angle glaucoma.  An LPI is a laser procedure to put a small hole through the iris.  This hole allows equalization of pressure across the iris which allows the iris to fall away from the internal drainage system of the eye thereby opening the access to the drain.  Before your laser a number of diagnostic tests are completed to determine the degree of angle opening.

Argon Laser Iridoplasty

This laser is done for narrow angle glaucoma.  At your follow up appointment following an LPI, the Doctor will note whether the LPI was successful in opening the narrow angle (opening access to the internal drainage system of the eye).  If it does not, a procedure using the Argon laser is the used to further open the angle and increase access to the drain.

YAG Capsulotomy

This laser eliminates a thickened membrane which has developed on the back surface of your lens implant following a cataract surgery.

Selective Laser Trabeculoplasty- SLT

This laser treatment for Glaucoma uses short pulses of low-energy to improve drainage and lower eye pressure.  This laser requires two visits to complete (minimum 3 weeks apart).

Diagnostics

Humphrey Visual Field

This is a visual eye examination that can detect dysfunction in central and peripheral vision which may be caused by conditions such as Glaucoma, strokes and compressive lesions on the optic nerve.

Optical Coherence Tomography - OCT

This is a computerized imaging technique that uses laser light recreate a 3-D image. It is very useful for analyzing the anatomy of the optic nerve and retina in diseases like Glaucoma, Macular Degeneration, and Diabetic Retinopathy.

Retinal Photography

Photo documentation of the inside of the eyes is an important aspect in diagnosing and managing ocular health throughout the years. The anatomy of the optic nervce, macula, and retina can be reviewed with your eye doctor during your appointment.

Heidelberg Retinal Tomography - HRT

Using a special scanning laser a cross section of the optic nerve is rendered. Subtle structural changes to the optic nerve are captured with the HRT and help identify Glaucoma damage before patients notice any changes in vision and often before it is identifiable on the visual field test.

Anterior Segment OCT - VISANTE

This is an OCT specifically designed for anterior segment imaging. It is the latest in technology to assess and follow the characteristics in angle anatomy.

IOL Master

This is the most accurate way to measure your eye prior to cataract surgery. The technique uses a laser technology to determine the power of the intraocular lens that will be implanted.

Special Instructions:

• Contact lens wear prior to IOL or A-scan measurements can change the results.
• We recommend No Soft CL wear for 7 days prior to measurement.
• We recommend No Hard CL wear for 21 days prior to measurement.

CORNEAL TOPOGRAPHY

The corneal topography maps the cornea and is beneficial for patients undergoing cataract surgery requiring specialty lenses such as TORIC or multifocal lenses.

A-Scan

A standard ultrasound technique used to measure the length of the eye and the thickness of the lens for cataract surgery.

B-Scan

An ultrasound of the globe often ordered when there is a poor view into the eye.

Ultrasound Biomicroscopy - UBM

An ultrasound used to characterize the anatomy of the front part of the eye, especially the angle of the eye and the area behind the iris.

DIURNAL TESTING

Measures intraocular pressure (IOP) over the course of one day starting at 8 am then approx. every 1.5 hours thereafter until 5 pm. Patients take their eye drops as they normally would and bring them to this session if they take them during the day. Patients can leave the clinic between pressure readings but must return in time for the next IOP reading.

Wave Front Analysis

Analysis of the way a wave front of light passes through the cornea and crystalline lens, which are the light focusing components of the eye. Distortions that occur as light travels through the eye are called aberrations, representing specific vision errors. These are characterized by the wavefront analysis and used to determine the type of refractive correction that should be performed.
