Advanced Diagnostic and Surgical Technology

At North Toronto Eye Care, we believe that progressive technology and high-quality care go hand-in-hand. We offer a variety of advanced technology options to serve the range of your eye care needs.

Corneal and Cataract Diagnostics

  • A-Scan: An A-Scan, or Amplitude Scan, is a diagnostic test that provides data on the length of the eye from the cornea to the retina, which can assist in the diagnosis of certain visual disorders. Most commonly, the A-Scan is used to calculate intra-ocular lens power to be used in cataract surgery.View Video
  • Zeiss IOLMaster: The Zeiss IOLMaster allows for the precise measurement of boundaries for IOL implantation, measuring corneal thickness, anterior chamber depth, lens thickness, axial length, and more. Using the Zeiss IOLMaster, our team can accurately measure the best IOL strength needed to provide our patients with the best vision possible.
  • Lenstar LS 900: The Lenstar LS 900 improves surgical accuracy by providing surgeons with precise measurements of the eye. This technology measures axial length, corneal thickness, lens thickness, eye curvature, and more. By providing a thorough analysis of the eye, we are able to provide more precise surgical outcomes from cataract surgery.
  • OPD-Scan III: The OPD-Scan III is an advanced vision-assessment system produced by NIDEK. Combining wavefront aberrometry, corneal topography, autokeratometry, autorefractometry, and pupillometry. This system provides an accurate analysis of corneal aberrations, such as astigmatism, and thorough analysis of an individual’s visual acuity
  • Nidek BCVA Machine: The Nidek autorefractor provides accurate BCVA (Best Corrected Visual Acuity) measurements. The autorefractor works by measuring how light is impacted as it reflects through the eye, helping to determine the vision correction needed by the patient.

Refractive Diagnostics

  • Pentacam: Pentacam technology is used to perform a Pentacam Scan, which collects images of the anterior segment and supplies 3D imagery. The process lasts under two seconds, and any eye movements are corrected as they are captured. Commonly used to collect measurements and assess patients for laser vision correction, the Pentacam can also provide cataract analysis and detect Keratoconus.
  • Pupilometer: The pupillometer is used to analyze pupil response or the dilation of the pupil in reaction to different stimuli. In some instances, the pupil will be measured in dark conditions to assess a risk for night time vision problems following LASIK eye surgery.

Retina

  • Argon Laser: The Argon Laser is a gas laser, most commonly used for retinal therapy. The Argon Laser stimulates the retina to reduce swelling, create small scars and cauterize blood vessels, or to prevent the extension of retinal tears. This laser is extremely precise and is additionally used in the treatment of glaucoma and diabetic eye disease through retinal phototherapy.

  • Bscan- Nidek: B-Scan ultrasonography is used in the assessment of ocular and orbital eye diseases. The B-Scan provides a cross-sectional image of the eye and its orbit, allowing physicians to view the lens of the eye, choroid, sclera, vitreous, and retina. B-Scan is useful in the diagnosis of retinal detachment, tissue damage, tumors, vitreous hemorrhage, foreign bodies, and more. The scan is painless and provides diagnostic opportunities for patients whose eyes may be difficult to evaluate otherwise.
  • Nidek Fundus Camera: Fundus photography uses high-powered lenses to take images of the back of the eye. Our physicians are able to then use the imagery to assess the overall health of the eye and monitor any changes that occur over time. This is a commonly performed in-office test, is painless, and does not involve any radiation.

  • Pentacam: Pentacam technology is used to perform a Pentacam Scan, which collects images of the anterior segment and supplies 3D imagery. The process lasts under two seconds, and any eye movements are corrected as they are captured. Commonly used to collect measurements and assess patients for laser vision correction, the Pentacam can also provide cataract analysis and detect Keratoconus.

Glaucoma

  • Tango SLT/YAG Combination Laser: Selective Laser Trabeculoplasty (SLT) is performed as an in-office procedure to reduce intraocular pressure caused by glaucoma. Targeting only cells containing melanin, the laser leaves the surrounding tissue of the eye intact and unaffected. The procedure improves the flow of fluids in the eye, helping to lower intraocular pressure.
