Clinical Trial Summary

This study is designed to determine the most effective post-operative care to relief the patient's discomfort after pterygium excision surgery.

Clinical Trial Description

This is a prospective, randomized controlled trial. 50 patients with primary pterygium in both eyes for whom surgery was advised, will be recruited to the study. Criteria for pterygium excision surgery is mostly cosmetic, local eye symptoms, or visual impairment.

The following data will be collected and analyzed:

1. Demographic data such as: age, gender

2. Clinical data: best-corrected visual acuity (BCVA) full biomacroscopy examination, before surgery and at post-operative day (POD) 1 and 3

3. Symptoms and discomfort: Visual Analogue Scale (VAS) score and pain killer use. The differences in these variables values preoperatively and on the first and 3rd postoperative day will compared between the two treated eyes.

Surgical technique and postoperative care

All patients will be operated for the same pterygium excision under local anesthesia in the formal accepted surgical method. All patients will be treated with ofloxacin drops + dexamethasone drops four times daily during the first postoperative week. The only difference is that one group will be bandaged with tight bandage patching and the other with therapeutic contact lenses (TCL) only for the first 24 hours.

Patient-centered outcome

Discomfort and pain will be evaluated on the follow-up meeting on the first and 3rd postoperative day. The patient will be asked to rate pain and discomfort for each operated eye on pain scale of VAS ranking the pain on a line from No pain at 0 cm to worst possible pain at 10 cm and the estimated pain given by the patient's translation of pain into spot on a line.

Patients will also be queried about the number of hours during which they feel pain, and the number of pain killers used ( every patient will be given prescription for 3 tabs of Paracetamol 500 mg (giving no drugs sensitivity for paracetamol) on POD 1 & 3).

Their sleep quality will rated according to whether they reported having a full night's sleep and the number of times they were awoken due to pain/discomfort.

Statistical analysis

The t test was used to calculate differences in numerical variables (VA, hours of pain, number of pain killers, etc.). Non-parametric Wilcoxon Mann-Whitney was used to calculate differences in non-numerical variables such as pain level (VAS scale). Chi-square analyses were used to calculate proportional group differences (e.g., use of pain killers and sleep pattern). The overall significance level was set to a value of 0.05. The statistical analysis was carried out using Microsoft Excel 2013. ;
