This prospective longitudinal observational study aims to assess stereopsis recovery in strabismic patients at one month and three months post-corrective surgery. The study will be conducted at Mayo Hospital, Lahore, and Sajjad Eye Center, Burewala, with a sample size of 34 using a purposive sampling technique. Eligible participants include patients aged ≥5 years undergoing strabismus surgery for esotropia, exotropia, or vertical deviations, with best-corrected visual acuity (BCVA) of 6/12 in both eyes. Patients with previous strabismus surgery, amblyopia, neurological conditions, or sensory strabismus will be excluded.

Baseline assessments include visual acuity (Snellen Chart), ocular alignment (cover-uncover and prism cover tests), and stereopsis (Titmus Fly Test). The same tests will be repeated one month and three months post-surgery to evaluate changes. The study aims to determine whether strabismus surgery enhances binocular function and stereopsis, helping guide future treatment strategies. Data will be analyzed using paired t-tests to assess differences over time.

Inclusion Criteria:

• Patients (≥5 years and adults) undergoing strabismus surgery for: esotropia, exotropia, vertical deviations (hypertropia or hypotropia)
• Best corrected visual acuity (BCVA) of 6/12 in both eyes
• Willingness to attend follow-up visits at 1 month and 3 months post-surgery.8

Exclusion Criteria:

• History of previous strabismus surgery
• Amblyopia
• Neurological and systemic conditions affecting vision
• Uncontrolled nystagmus and sensory strabismus
• Patients unable to complete stereopsis testing due to cognitive or physical limit
