Abstract
To incorporate advanced corneal imaging into a new keratoconus classification system that utilizes posterior curvature, thinnest pachymetry, and best-corrected distance vision (CDVA) in addition to standard anterior parameters. A total of 672 eyes of 336 normal patients were imaged with the Oculus Pentacam HR. Anterior and posterior radius of curvature measurements were taken using a 3.0 mm zone centered on the thinnest area and corneal thickness was measured at the thinnest point. Mean and standard deviations were recorded and anterior data were compared to the existing Amsler-Krumeich (AK) classification. A total of 672 eyes of 336 patients were analyzed. Anterior and posterior values were 7.65 ± 0.236 mm / 6.26 ± 0.214 mm respectively and thinnest pachymetry values were 534.2 ± 30.36 um. Comparing anterior curvature values to AK staging yielded 2.63, 5.47, 6.44 standard deviations for stages 1, 2, and 3 respectively. Posterior staging uses the same standard deviation gates. Comparative pachymetric values yielded 4.42, and 7.72 standard deviations for stages 2 and 3 respectively. A new keratoconus staging system incorporates posterior curvature, thinnest pachymetric values, and distance visual acuity in addition to the standard anterior curvature and consists of stages 0 to 4 (5 stages), closely matches the existing AK classification stages 1 to 4 on anterior curvature. The new classification system by incorporating curvature and thickness measurements based on the thinnest point, as opposed to apical, better reflects the anatomic changes in keratoconus.

Abstract
To discuss and summarize the indications, contraindications and results in refractive surgery for keratoconus. Keratoconus is an ectatic corneal disease characterized by a progressive corneal thinning and irregular astigmatism that negatively impact in the visual function and the optical quality of the patients. The refractive surgery in keratoconus has been discussed by several authors. The two primary lines of action are phakic lens implantation and corneal tissue ablation using photorefractive keratectomy. The use of phakic intraocular lenses (IOLs) to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity. The use of phakic IOLs to correct myopia and compound myopic astigmatism associated with keratoconus is gaining popularity. According to a recent study by our group the safety of this procedure in visual terms is high (post-CDVA/ pre-CDVA = 1.19 ± 0.29). It is also an effective operation (post-UDVA/pre-CDVA = 0.90 ± 0.26). Alio JL, Sanz-Díez P. Phakic Intraocular Lenses in Keratoconus. Int J Kerat Ect Cor Dis 2015;4(3):103-106.

Abstract
Presenting the course of visually disabling corneal infiltration post uneventful collagen cross-linking (CXL) in a 23 years old male with bilateral keratoconus. A 23 years old male with bilateral keratoconus underwent cross-linking of left eye with indigenous 0.1% riboflavin dye and 370 nm ultraviolet A irradiation. This patient had an uneventful successful cross-linking performed in right eye 6 months prior with good recovery of vision to LogMAR (6/9 Snellen). Patient developed diminution of vision, along with redness of eye, photophobia and watering on 3rd day after uneventful cross-linkage. Examination revealed very poor vision; diffuse corneal clouding with multiple superficial stromal infiltrates and incomplete corneal epithelization. A provisional diagnosis of infective keratitis was made, Sterile infiltration post-CXL requiring intense topical steroids is a rare complication of CXL and needs to be differentiated from infective keratitis.

Abstract
We aim to share our experience in the management of a 19 years old female patient, who presented to Princess Haya Military Hospital in Aqaba, Jordan, with a very aggressive keratitis. A 19 years old female patient with 1 year history of keratitis that did not resolve despite several treatment strategies tried elsewhere, presented to the eye clinic in Aqaba. Ocular examination showed signs of Acanthamoeba keratitis with perineuritis. Corneal cultures were not informative. Corneal biopsy showed a mixed Candida and Acanthamoeba growth. The patient was started on topical and oral anti-amoebic and antifungal treatment (antiamoebic drops brought from UK). Improvement was drastic after 2 weeks of treatment. The patient maintained a chronic low infective state and scarring of the cornea. She received therapeutic and visual karatoplasty 3 months later. Patient is now 12 months after her PKP. The cornea is clear and vision is 6/12 unaided. Cases of mixed fungal and amoebic keratitis are very rare. Prompt treatment and diagnosis is essential for recovery. Controversy still exists on the use of steroids after corneal transplantation for treatment of chronic fungal keratitis. Management should be tailored to each individual case.
