Keratoconus
Assessment of corneal steepening, monitoring for progression, and determining whether cross-linking or visual rehabilitation options are needed.
Evaluation and follow-up of corneal conditions such as keratoconus and recurrent corneal erosions, corneal neovascularization, opacities, inflammation, and ocular-surface disorders, with an individualized management plan for each case.
Symptoms, causes, and treatment vary. Management therefore begins with a detailed examination of the cornea, ocular surface, and vision.
Assessment of corneal steepening, monitoring for progression, and determining whether cross-linking or visual rehabilitation options are needed.
Sudden episodes of pain, often on waking, caused by poor adhesion of the corneal surface layer.
Assessment of the cause, activity, and effect of new vessels on corneal clarity and vision.
Determining the location, depth, and visual impact of opacity, followed by discussion of appropriate treatment options.
Urgent evaluation of pain, redness, photophobia, and discharge, with treatment directed to the cause.
Monitoring corneal dystrophies and deposits and assessing their effect on vision and comfort.
Keratoconus causes corneal thinning and irregular steepening and may lead to irregular astigmatism, blur, ghost images, or frequent prescription changes. Follow-up therefore relies on corneal maps and thickness measurements compared over time.
The cause may be recurrent corneal erosion, in which the superficial epithelial layer separates because it does not adhere properly to the layer beneath. Episodes may recur on waking or when opening the eye, even without a new injury.
Book a Corneal Surface AssessmentEpisodes can appear months or years after a corneal scratch from a fingernail, paper, or sharp object.
Some corneal disorders weaken the adhesion of superficial cells.
Dry eye and meibomian gland dysfunction may increase eyelid friction on the corneal surface and delay healing.
Treatment depends on episode frequency, defect location, loose epithelium, and the condition of the ocular surface and dry eye.
If the corneal surface remains open and does not heal within the expected period, a persistent epithelial defect may be present and may require broader evaluation of corneal nerves, inflammation, infection, diabetes, medications, and the ocular surface.
The corneal endothelium is the inner layer responsible for pumping excess fluid out of the cornea and maintaining clarity. When these cells weaken, as in Fuchs endothelial dystrophy or after certain surgeries, the cornea may swell and vision may become blurred, with glare and light sensitivity that may be more noticeable on waking.
Corneal transplantation is not one operation for every condition. In many patients only the damaged layer needs to be replaced, while healthy layers are preserved, allowing a more individualized surgical plan.
Replacement of the endothelial layer and thin posterior membrane in conditions such as Fuchs dystrophy or endothelial failure, while preserving most of the patient’s cornea.
Replacement of the endothelium together with a thin supporting stromal layer, selected in certain cases depending on ocular condition and previous surgery.
Used for selected keratoconus and anterior scar cases while preserving the patient’s healthy endothelium.
Considered when disease or scarring involves the full corneal thickness or lamellar transplantation is not appropriate.
We review disease location and depth, lens status, retina, eye pressure, and visual expectations before selecting the transplant type.
Follow-up includes monitoring corneal clarity, eye pressure, wound healing, and response to postoperative treatment.
New vessel growth may be associated with inflammation, contact lenses, reduced oxygen, or previous injury. We assess vessel activity, depth, cause, and effect on corneal clarity before building the appropriate plan.
Identify the nature and timing of blur, pain, redness, and light sensitivity.
Assess the corneal surface, clarity, thickness, and shape when needed.
Relate examination findings to previous injury, contact lens use, and associated disease.
Select treatment and follow-up intervals and explain warning signs requiring earlier review.
Severe pain, marked redness, significant light sensitivity, discharge, direct injury, or a sudden drop in vision should prompt urgent eye assessment.
Book an appointment for corneal assessment and discussion of follow-up or treatment options based on examination findings.
