The analysis of cornea morphology using corneal topographers is a clinical practice for the diagnosis of keratoconus in contact lens fitting. The recently technique has developed with the possibility of achieving a great number of measuring points of both anterior and posterior corneal surfaces in cornea. Also these data are used to extract a series of topographic valuation indices that permit to offer the most exact clinical diagnosis of keratoconus in contact lens fitting. This study describes the technologies in which current corneal topographers are based on the morphological characteristics that the keratoconus status observe on corneal surface. Therefore, this paper can provide that the analysis of corneal topographers applied for the diagnosis of keratoconus in contact lens fitting.

Purpose: To investigate the corneal thickness and anterior chamber depth (ACD) of eyes with Keratoconus in the Korean population with the Pentacam. Methods: The subjects consisted of 84 eyes from Keratoconic adults aged 7-59 years during 2010. The thinnest area, apex zone, and pupil centre of the corneal thickness were measured using the Pentacam pachymetry. ACD value was also measured with Pentacam. Results: There was a statistically significant relationship between thickness of the cornea at the apex area and the pupil centre (p=0.0001). However, there was no statistical difference (p>0.5) in the mean thickness of thinnest area, apex zone, pupil centre of cornea between right eye and left eye. Also, correlation between ACD and corneal thickness in all subjects had no statistical differences (p>0.05) in all subjects. Conclusion: These results suggested that the regional thickness of cornea and ACD with Pentacam can provide correct and useful diagnostic information of the morphology of Keratoconus for the RGP contact lens and diagnosis of abnormal corneal refraction surgery.

각막곡률반경은 RGP 렌즈를 착용한 대학생(1980~1984년)을 대상으로 측정하였다. 대상자는 187명으로 여자(167), 남자(17) 그리고 원추각막환자(3)이었다. 각막곡률반경은 전체대상자의 평균치가 7.77mm이었고, 좌안과 우안의 측정치 역시 7.77mm이었다. 눈의 수평, 수직경선의 측정치는 7.88mm, 7.65mm이었다. 남자와 여자의 경우는 모두가 수평이 수직경선보다 동일하게 0.22mm 크게 조사되었다. 성별에 따른 곡률반경의 차이는 남자의 경우 평균치가 7.84mm으로 여자의 경우보다 0.08mm 정도 크게 측정되었고, 좌, 우안의 크기는 차이가 없었다. 원추각막환자는 곡률반경의 평균치가 6.86mm으로 정상인 조사대상자의 평균치보다 0.91mm 작게 조사되어 차이가 큰 것으로 나타났다.
