During stage 1 or the early stage of keratoconus, very slight corneal distortion is observed. Purpose To derive limits of metric keratoconus indices for classification into keratoconus stages. The proposed system closely matches the existing AK classification stages 1-4 on anterior curvature. In the early stages, keratoconus may cause slightly blurred or distorted vision. In its earliest stages, keratoconus causes slight blurring and distortion of vision and increased sensitivity to glare and light. As keratoconus progresses and worsens, glasses are no longer capable of providing clear vision, and patients need to wear a contact lens, usually a hard contact lens. It may therefore be beneficial to know the amount of change/deviation in OCT measurements in keratoconus patients and to report which parameters exceed the standards so that OCT can be used to correlate the stage of keratoconus with the extent of the ocular disorder. In our study a value of 0.52 was classified as suspect, but we found a cut-off point of 0.77, as shown in Table 5.

The irregular shape of the keratoconus cornea degrades image quality so vision correction is needed in most keratoconus patients.

At Total Eye Care, our keratoconus experts find that over 90% of patients their patients are successfully treated with contact lenses. Measurements were not significantly different in all patients and subgroups and showed high correlation for the corneal thicknesses of the entire cornea in different stages of keratoconus. An improved definition of the different stages of keratoconus will aid in the assessment of candidates for corneal refractive surgery and research into potential treatments for the condition, said Stephen Tuft FRCS, Moorfields Eye Hospital, London UK. Design Validity and reliability analysis of diagnostic tools. Aim . Specular microscopy was not possible in stage 4. The aim of this study was to compare the central and peripheral pachymetric measurements determined with Sirius system and Visante OCT and evaluate the agreement between them at different stages of keratoconus.

Keratoconus may progress for 10-20 years and then slow or stabilize. Investigators considered postoperative best-spectacle corrected visual acuity (BSCVA), spherical equivalent refraction, mean keratometry, keratometric astigmatism and complications based on keratoconus stage. The symptoms are extremely mild and therefore, sometimes, they cannot be detected. Misconceptions And Myths About Keratoconus (KC) in Miami. – Early or mild keratoconus, which entailed 5- to 8-degree deviation of horizontal axis.

The severity of irregular astigmatism at the same stages of KC had a significant effect on OCT measurements. Because collagen cross-linking is most effective during the early stage of keratoconus, early detection is key. Later, you may have to be fitted with rigid, gas permeable contact lenses or other types of lenses, such as scleral lenses. Early to Intermediate Stages.
