To study the effect of artificial tear instillation on ocular aberrations in dry-eye patients.
Research, Development and Innovation Department, Instituto Oftalmológico de Alicante, Alicante, Spain.
Ocular aberrations (total, spherical-like, and coma-like) were measured with a Hartmann-Shack aberrometer before and after artificial tear instillation (immediately and 10 minutes later) in 15 eyes of 15 dry-eye patients.
Optical aberrations showed a statistically significant reduction after artificial tear instillation (P<.01). Total aberrations decreased on average by a factor of 2 to 3 times immediately after instillation; the reduction was maintained after 10 minutes (P>.01).
After artificial tear instillation, the reduction in optical aberrations associated with an increasingly irregular tear film may cause an improvement in the optical quality of dry eyes. Wavefront analysis facilitates the evaluation of improvement in optical quality after artificial tear instillation in patients with dry eye.
研究人工泪液滴眼对干眼患者眼像差的影响。
西班牙阿利坎特眼科研究所研发与创新部。
使用哈特曼 - 夏克像差仪测量15例干眼患者15只眼在滴入人工泪液前、滴入后即刻和10分钟后的眼像差（总像差、类球差和类彗差）。
滴入人工泪液后，光学像差有统计学显著降低（P <.01）。滴入后总像差平均立即降低2至3倍；10分钟后仍保持降低（P >.01）。
滴入人工泪液后，与泪膜日益不规则相关的光学像差降低可能会改善干眼的光学质量。波前分析有助于评估干眼患者滴入人工泪液后光学质量的改善情况。
