38 Oral Presentationimpaired adults attending the Vision Rehabilitation Centres, L V Prasad Eye Institute, Hyderabad,India. Rasch analysis was used to assess the psychometric performance of the entire IND-VFQand its three subscales.Results: Response categories were used as intended to resulting in retention of original ratingscale. The IND-VFQ had good person separation reliability, PSR (i.e. measurement precision)but lacked unidimensionality (i.e. measured more than one construct) invalidating use oftotal IND-VFQ score. Furthermore, items did not fit the construct, performed differentlyacross subgroups (i.e. differential item functioning) and one subscale was dysfunctional (visualsymptoms). However the items were matched well to the participant’s ability (targeting).Segregating items into 2 constructs (visual functioning, VF, scale and psychosocial impact, PI,scale) provided unidimensional measures but some items still misfit in each construct. Deletionof misfitting items provided valid measurement of each construct with adequate PSR (0.87 forVF and 0.81 for PI scale) and targeting (-0.90 logits for VF and -0.29 logits for PI scale).Conclusions: The IND-VFQ consists of two separate unidimensional constructs: visualfunctioning and psychosocial impact. The 11-item VF and 4-item PI scales have good psychometricproperties and are unidimensional.IPT 014Should the Current Ophthalmology Residency Training in India Focus more onSkill Transfer!Taraprasad Das, Siddharth Kesarwani, Sujata Das, Sriakant K Sahu, Suryasnata Rath, SanghamitraDash, Soumyava Basu, Tapas R Padhi, Sudipta Parida, Savitri SharmaL V Prasad Eye Institute, Bhubaneswar Campus, India.Purpose: To assess the current learning level and evaluate the immediate impact of supervisedskill transfer to ophthalmology residents in an Eastern India state.Methods: In a day long structured skill transfer program 7 common skills essential toophthalmology residency program was taught. The residents used the visual analogue scale(VAS) at 0-10 scale at beginning and end of the program.Results: Twenty-seven of 32 residents that attended the program completed both pre and postsession VAS score. The sore improved from mean 1.9 to 6.47 and was significant (p
