Comparing success rates of two surgical techniques for involutional entropion of the lower eyelid: the everting sutures and the lateral tarsal strip.

INTERVENTION: Patients suffering from primary involutional entropion will participate in the study. Patients will be randomised to everting sutures technique (commonly used) and to lateral tarsal strip technique (commonly not used as standard practice). The lateral tarsal strip technique: Cantholysis of the lateral palpebral ligament. Preparation of an outer tarsus flap (sling) by removing the dermis, the orbicularis muscle and the conjuctiva. Flap fixation by using sutures 5.0 to the temporal orbit periosteum . Wound restorarion by using 6.0 sutures. These procedures will be performed by the qualified ophthalmologist Elias Nakos expert in oculoplastics. CONDITION: Involutional entropion of the lower eyelid. PRIMARY OUTCOME: Quality of life by using the VQF‐25 Questionnaire preoperatively and at six months follow‐up. Success rate. ; The success is assessed by clinical examination. At the follow‐up visit, eyelid is asessed in the primary and downgaze position. ; The patients will also asked to squeeze their eyelids closed to detect any latent recurrence. ; The surgical success is defined as complete resolution of the inward eyelid margin rotation and symptoms. ; ; SECONDARY OUTCOME: Complications rate by using clinical examination and asking the patient for possible problems postoperatively. INCLUSION CRITERIA: Lower eyelid involutional entropion.
