Correction Methods In Patients With Keratoconus

Purpose – to use hybrid lenses for correction in patients with keratoconus.

National Opthalmology Centre named after acad. Zarifa Aliyeva

The study included 28 patients (36 eyes) diagnosed with stage 1-3 keratoconus who applied to the excimer laser department of the National Centre of Ophthalmology named after acad. Zarifa Aliyeva for a year. 

Objective and subjective examination methods were used – biomicroscopy, refractometry, tonometry, keratotopography, Schirmer's test, determination of visual acuity without correction and with correction by contact lenses.

Patients underwent vision correction using hybrid contact lenses (SynergyEyes, Ultrahealth, USA).

To examine the patients, diagnostic lenses were fitted, to observe the formation of bubbles, the cornea was stained with fluorescein and examined under a biomicroscope with a blue pen objective using a slit lamp.

Patients were under observation for 1 year. Despite long-term use of the lens, the topographic and refractive indices remained stable.

Based on the results of observations, keratometric parameters, spherical and cylindrical parameters were assessed in patients. As keratometric parameters decreased during lens use, the spherical and cylindrical parameters changed significantly.

In 15 of 36 examined eyes visual acuity reached 1.0; in 11 eyes – up to 0.7; in 7 eyes – up to 0.6, which is twice as much as with glasses. Due to the increase in visual acuity during correction, the use of lenses has retained its importance.

As can be seen from our observations, high visual acuity is achieved due to the creation of a spherical smooth optical surface on the cornea as a result of correction with Ultrahealth soft hybrid lenses. This helps to improve the efficiency of life and professional activities of patients compared to glasses.

 Ultrahealth hybrid lenses are the most advanced hybrid contact lenses and are an ideal choice for patients with keratoconus and irregular corneas.
