CLEAR - Medical use of contact lenses.

The medical use of contact lenses is a solution for many complex ocular conditions, including high refractive error, irregular astigmatism, primary and secondary corneal ectasia, disfiguring disease, and ocular surface disease. The development of highly oxygen permeable soft and rigid materials has extended the suitability of contact lenses for such applications. There is consistent evidence that bandage soft contact lenses, particularly silicone hydrogel lenses, improve epithelial healing and reduce pain in persistent epithelial defects, after trauma or surgery, and in corneal dystrophies.

Defining success in infant penetrating keratoplasty for developmental corneal opacities.

Background And Purpose: Neonatal corneal opacities (NCO) are one of the common causes of visual impairment in infants. We present the two infants with penetrating keratoplasty (PKP) for unilateral NCO with different visual and graft outcomes, and illustrate the importance of timing of surgery, importance of visual rehabilitation, and the lack of necessity of a clear graft to achieve reasonable visual function in infants with NCO.

Patients And Methods: Two infants with unilateral NCO (Peters anomaly) underwent PKP at age of 5.

Unilateral keratoconus in a child with chronic and persistent eye rubbing.

Purpose: To report a case of unilateral keratoconus in a 7- year-old female, secondary to chronic persistent eye-rubbing in the absence of any systemic condition.

Design: Observational case report.

Methods: In the case of this child, no organic cause was found to explain the onset of keratoconus other than persistent eye-rubbing in the affected eye.
