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.

Cataract Surgery Technology

  • Catalys Femto Laser: Designed specifically for laser cataract surgery, the Catalys Femto Laser uses 3D imaging, surface mapping, and advanced software to produce precise surgical outcomes and a highly customizable surgery.

  • LenSx Femtosecond Laser: The LenSx system, created by Alcon, is a femtosecond laser used in cataract surgery that replaces the need to use a hand-held blade, as is used in traditional cataract surgery. Using laser technology, the incisions needed to perform cataract surgery are more precise and produce extraordinary results. This system may provide enhanced outcomes for astigmatic patients as compared to traditional cataract surgery, as well.

  • OPMI Lumera 700 Microscope: An ophthalmic microscope which helps improve surgical accuracy, the OPMI Lumera 700 provides high-quality, real-time visuals of the anterior and posterior segments of the eye during surgery.
  • Verion Image Guided System: The Verion Image Guided System is designed to assist physicians in mapping and planning cataract surgery, maximizing accuracy and efficiency during the cataract procedure. The Verion system takes high-resolution images of the eye and maps out details and measurements pertinent to a successful cataract procedure. Each step of the surgery is customized to the individual’s eye based on the figures provided.
  • Clarion Yag Laser: A YAG Laser (Yttrium-Aluminum-Garnet) uses highly focused laser light to create small openings in the posterior capsule. The laser then clears out the clouded membrane that can sometimes form after cataract surgery.

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.


  • 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.

  • Zeiss OCT: OCT (Optical Coherence Tomography) uses waves of light to produce imagery of the retina, allowing our ophthalmologists to see the distinctive layers of the retina. This imagery assists in the diagnosis of retinal conditions such as age-related macular degeneration or diabetic eye disease. The OCT imaging test is non-invasive. Our practice additionally offers the Zeiss OCT with Angioplex, providing high-resolution, 3D angiography images of the retinal and choroidal microvasculature. Learn more about Zeiss OCT technology.

  • Antares Topographer: Provides advanced corneal topography, dry eye diagnostics, and contact lens fittings in one device. Able to assess dry eye and provide tear film analysis and Meibomian Gland Dysfunction analysis and classification.
  • Atlas Topographer: The Atlas Topographer is a tool that creates a 3D map of the corneal surface of the eye. The Atlas Topographer evaluates a series of data points, evaluating changes in the surface of the eye and its curvature. By providing a detailed visual of the shape and power of the cornea, our physicians are able to use these details in the diagnosis and treatment of eye conditions, for contact lens fittings, and for planning refractive procedures like LASIK eye surgery.

  • Endothelial Cell Count/Specular Microscope: The corneal endothelium is the innermost layer of the cornea, which helps to control the amount of fluid entering the cornea. Excess fluid can cause vision problems such as swelling and vision loss. An endothelial cell count (using a specular microscope) is important to detect and monitor the loss of endothelial cells caused by trauma or Fuchs endothelial dystrophy and can help to determine whether surgery is needed to repair the corneal tissue.

  • 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.


  • 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.

  • Zeiss Visual Field Analyzer: The Humphrey® Field Analyzer (HFA™) is used in the diagnosis and management of glaucoma. This device helps to measure peripheral vision, which is affected by glaucoma before an individual’s central vision. The tool can help assess changes in peripheral vision and to help screen for the disease in conjunction with other testing.

Dry Eye

  • Lipiscan: The LipiScan tests the meibomian glands, the part of the eye most likely to cause dry eye. This system provides high-definition images to show blockages or irregularities. The LipiScan is quick, efficient, and provides highly accurate images to assist your doctor with the diagnosis.
  • LipiFlow: LipiFlow treatment applies heat and massages the meibomian glands through pulsating eyepieces, called activators. This helps to evacuate blockages in the glands and promote oil production in the eye.
