  author={Lamis Abdelaziz and Ramez Barbara and Adel Barbara},
Keratoconus (from Greek meaning horn-shaped cornea) is a degenerative, ectatic disease of the cornea, causing corneal thinning and remodelling into a more conical shape. 1 Symptoms include blurring of vision, and a gradual decline in visual acuity. 1 It is usually bilateral, but can affect each eye at different severities. 1 There are various treatment modalities, both surgical and nonsurgical, both simple and more invasive. Here, we review the history of the development and advances of the… 
Evolution of Keratoconus: From Diagnosis to Therapeutics.
Karatoconus diagnosis and management have grown tremendously since the first description in 1736, but there is still much to learn about keratoconus and its management.
Evolution of Keratoconus : From Diagnosis to Therapeutics Die Evolution in der Behandlung des Keratokonus : von der Diagnose zur Therapie
This review describes the evolution of the diagnosis and treatment of keratoconus from the earliest written description to present day. The first description was provided in 1736 by Benedict Duddell
Surgical Correction of an Inverse Astigmatic Keratotomy following Penetrating Keratoplasty in a Patient with Keratoconus
The case of a post-PKP AK that was performed inversely by mistake in a private practice and corrected the remarkably high astigmatism that was created with the previous inverse procedure is reported.
Long-term Results of Mini Asymmetric Radial Keratotomy for the Treatment of Keratoconus
MARK improved both mean keratometry and mean pachymetry, thus halting the progression of keratoconus, while improving visual acuity, and should be considered as one of the conservative treatments for moderate to mild progressive ker atoconus.


Keratoplasty in treatment of keratoconus.
In some cases the deformity, after beginning to develop, remains stationary, without tendency to become worse; this condition is designated as abortive keratoconus; the patient is still able to obtain fairly good vision with the aid of ordinary glasses, although this correction may require the use of high cylinders.
Keratoconus: Current understanding of diagnosis and management
This update is intended to inform the reader of the current understanding of diagnostic criteria, natural progression once diagnosed, alternatives for maximizing visual performance, and the influence of heredity for this fascinating corneal disease.
Asymmetric radial keratotomy for the correction of keratoconus.
Asymmetric radial keratotomy in keratoconus is designed to flatten the steeper central and paracentral areas of the cornea and is thought to be the treatment of choice for types I, II, and selected cases of type III ker atoconus.
Current surgical options for keratoconus.
Keratoconus is considered a contraindication to incisional refractive surgery such as radial keratotomy and laser in situ keratomileusis because of the corneal instability conferred by these procedures.

Above all, the astute corneal diagnostician must learn to appreciate irregular astigmatism and should train extensively with a manual keratometer to detect subtle yet very meaningful levels of preoperative keratoconus and irregularAstigmatism following refractive surgery.
Intacs for keratoconus.
Asymmetric Intacs implantation can improve both uncorrected and best spectacle-corrected visual acuity and can reduce irregular astigmatism in corneas with and without corneal scarring.
Zur Aesthesiometrie der Hornhaut nach refraktiver Hornhautchirurgie
The corneal sensibility was examined with the aesthesiometer of Draeger in patients after refractive cornea surgery and after epikeratophakia and it could be shown that after radialCorneal incisions the sensibility remains normal.
Ferrara intrastromal corneal ring segments for severe keratoconus.
Ferrara intrastromal ring segments appear to be an alternative for the treatment of severe keratoconus with early results.

It was found that current data do not support the notion that RK results in better visual outcomes than PRK and LASIK, and RK is not the preferred methodology because of its associated chronic visual and corneal health complications.
