Purpose
To study visual outcome and long-term complications in infants with primary intraocular lens implantation at a five year follow up
Setting
Pedaitric Cataract Services, Tertiary care institute, Chandigarh , India
Methods
Infants operated for congenital cataract with primary IOL implantation with a minimum follow up of four years, were recruited in the study. They were evaluated for visual acuity, refractive error, intraocular pressure, additional surgeries and their indications, long term complications like visual axis opacification and glaucoma. The main outcome measures were visual acuity, myopic shift and rate of additional surgeries. The rates of all the complications were compared between infants operated before 6 months of age and after 6 months of age. Factors responsible for large myopic shift ( more than or equal to 7DS) were evaluated separately.
Results
Seventy- one eyes of 42 infants with a mean age of 6.4± 0.4 months were studied. The mean follow up was 63.19 ± 0.3 months. The mean visual acuity was 6/30. The mean myopic shift was 6.3 DS ± 4.12 DS. The rate of additional surgeries was 26.7%. The main cause of additional surgeries was visual axis opacification, seen in 23% of eyes. Ocular hypertension was seen in 5 eyes. Large myopic shift showed a positive correlation with rate additional surgeries (p value=.002), immediate post operative refractive error (p value= .002) and PHPV (p value=.038). No correlation was seen between myopic shift and age. Visual outcome was not different between infants operated before 6 months of age versus those operated after 6 months.(p value= .958)
Conclusions
This study has shown a fairly reasonable visual outcome with low rate of additional surgeries in infants who underwent cataract surgery with primary IOL implantation. Factors which showed a positive correlation with large myopic shift included rate of additional surgeries (p value=.002), immediate post operative refractive error (p value= .002) and PHPV (p value=.038).
