- W3096804973 abstract "To describe ocular biometric parameters and the prevalence of corneal astigmatism as well as age and gender correlations in a population of cataract surgery candidates and to estimate the number of eyes that would be candidates for a toric intraocular lens (IOL). In consecutive patients requiring cataract surgery over a one-year period (June 2016 to June 2017), the following optical biometry measurements were performed on an IOLMaster 700 or Lenstar 900: axial length (AL), anterior chamber depth (ACD), lens thickness (LT), mean keratometry (K), flat keratometry (K1), steep keratometry (K2), corneal astigmatism (Cyl) and white-to-white diameter (WTW). Descriptive statistics for the demographic and biometric data were analyzed. The study sample included 6111 eyes of 3332 patients (59.3% women), with a mean age of 74.78 ± 9.7 years. The means of the compiled data are as follows: AL 23.58 ± 1.55 mm, ACD 3.08 ± 0.41 mm, LT 4.55 ± 0.52 mm, K 44.15 ± 1.54 diopters (D), K1 43.64 ± 1.57 D, K2 44.69 ± 1.61 D, Cyl 1.0 ± 0.81. D and WTW 11.88 ± 0.46 mm. The male patients had significantly larger eyes (higher AL, ACD and WTW) and flatter corneas (lower flat and steep K). Older patients had significantly lower AL, ACD and WTW, while their LT values were higher. Corneas became significantly steeper with age. 60.5% of eyes had less than 1 D of corneal astigmatism, while 3.1% had ≥ 3.0 D. Less than 1 D of corneal astigmatism was present in the majority of cataract surgery candidates. 3.1% of eyes were candidates for a toric IOL. This study provides useful information on inventory requirements for planning hospital resources. Décrire les paramètres oculaires biométriques et la prévalence de l’astigmatisme cornéen, ainsi que les corrélations avec l’âge et le sexe dans une population de candidats à la chirurgie de la cataracte et estimer le nombre d’yeux candidats à un IOL torique (TIOL). Chez les patients consécutifs devant subir une opération de la cataracte sur une période d’un an (juin 2016 à juin 2017), les mesures de biométrie optique suivantes ont été effectuées (IOLMaster700 ou Lenstar900): longueur axiale (AL), profondeur de la chambre antérieure (ACD), lentille épaisseur (LT), kératométrie moyenne (K), kératométrie la plus plate (K1), kératométrie la plus courbe (K2), astigmatisme cornéen (Cyl) et distance blanc à blanc (WTW). Des statistiques descriptives pour les données démographiques et biométriques ont été analysées. L’échantillon de l’étude comprenait 6111 yeux de 3332 patients (59,3 % de femmes) d’un âge moyen de 74,78 ± 9,7 ans. Les moyennes des données compilées sont les suivantes: AL 23,58 ± 1,55 mm, ACD 3,08 ± 0,41 mm, LT 4,55 ± 0,52 mm, K 44,15 ± 1,54 dioptries (D), K1 43,64 ± 1,57 D, K2 44,69 ± 1,61 D, Cyl 1,0 ± 0,81. D et WTW 11,88 ± 0,46 mm. Les patients de sexe masculin avaient des yeux significativement plus grands (plus grands AL, ACD et WTW) et des cornées plus plates. Les patients plus âgés présentaient une AL, un ACD et un WTW significativement inférieurs, tandis que les valeurs de la LT étaient plus élevées. Les cornées étaient significativement plus courbes avec l’âge. 60,5 % des yeux avaient moins de 1 D d’astigmatisme cornéen, tandis que 3,1 % avaient ≥ 3,0 D. Moins de 1 D d’astigmatisme cornéen était présente chez la plupart des candidats à la chirurgie de la cataracte. 3,1 % des yeux étaient candidats au TIOL. Cette étude fournit des informations utiles sur les exigences en matière de planification des ressources hospitalières." @default.
