Background: Pterygium is a progressive fibrovascular growth that invades the cornea. Surgical excision is the only curative treatment, but no technique reliably eliminates recurrence. We report outcomes of a graft-free modified geometric technique. Methods: Prospective study of 40 consecutive patients with primary nasal pterygium (Vaniscotte grades II–III) operated at Avicenne Military Hospital, Marrakech, between April and December 2025. No conjunctival grafting was used. Follow-up at day 1, day 15, and months 1, 3, and 6. Results: Mean age 52 years (range 30–75). Male-to-female ratio 4:1 (80% male). Mean operative time 12 minutes (approximately 40% shorter than the time required for conjunctival autografting). At 3 months: 70% of patients had minimal irritation; 65% showed a smooth conjunctival surface. Recurrence rate: 12.5% (5/40); all recurrences occurred between months 3 and 6. Conclusion: Modified geometric surgery achieved an 87.5% success rate at 6 months, comparable to conjunctival autografting, with reduced operative time and preservation of conjunctival tissue.
