Introduction: Astigmatic changes induced by upper lid repositioning may be a cause of blurred vision after upper eyelid procedures. We designed a study to document the astigmatic changes after ptosis correction surgery in children. Aim: The study aims at documenting the changes in astigmatism after ptosis correction surgery in 30 consecutive children seen in a Regional Institute of Ophthalmology. Material and Methods: 30 consecutive paediatric patients (4-12 years of age) of blepharoptosis were enrolled. The patients were subjected to a complete ophthalmic examination and ptosis evaluation. Keratometry and cycloplegic refraction were done pre and post- ptosis correction surgery. Observations and Results: The average pre-operative astigmatism was 1.28 while the average observed post- operative astigmatism was 1.71. The average post- operative change in astigmatism was 0.43 which was statistically significant. Conclusion: There is a significant astigmatic change following ptosis surgery in children. Mandatory visual acuity testing, refraction and post mydriatic correction are recommended in all paediatric patients with ptosis at the time of presentation and three months post surgery.
