ABSTRACT
Objective: To compare post-operative pain relieving effect of topical diclofenac 0.1 0,5% in Corneal Collagen Cross Linking [CXL] for patients diagnosed with keratoconus
Methods: This randomized controlled trial was carried out for six months from October 2016 to March 2017. We included young patients having keratoconus with k-readings greater than 47D and central corneal thickness more than 400 microns. All the patients received single dose one drop of topical diclofenac 0.1% to [Group-A] and ketorolac 0.5% to [Group-B] 30 minutes in advance of the corneal collagen cross linking [CXL] procedure. The CXL was performed with topical 0.1% riboflavin eye drops in 20% dextran as a photo sensitizer. After 36 hours of the CXL procedure, the postoperative intensity of pain was assessed verbally by patients with the help of visual analog scale [VAS] numbers from zero to five where 0 designated no pain 6 5 symbolized worst pain
Results: The study comprised sixty eyes of forty one patients. Out of total 16 were male while 25 female patients. The mean age of the patients was 24.27 +/- 2.93 years [range 20 to 29 years]. In the conclusive analysis, diclofenac 0.1% was used on 30 patients in Group-A and ketorolac 0.5% on 30 subjects in Group-B. Pain relieving scores in Group-A [diclofenac 0.1%] was 2.57 +/- 0.67 while in Group-B [ketorolac 0.4% treated arm] was 3.20 +/-0.61
Conclusion: Topical diclofenac 0.1% is statistically comparable to topical ketorolac 0.5% in precluding severity of pain after corneal collagen cross linkage operation
