Purpose:
|
To study the effects of inducing hypermetropia on myopic shift in children undergoing cataract surgery and primary intraocular lens(IOL)implantation
|
|
Methods:
|
This prospective study included99eyes with congenital cataract that underwent cataract surgery with IOL implantation.IOL power was chosen using SRKII based on the age of the patients to induce hypermetropia.The desired postoperative refractions were7,5,3.5,2.5,1.5 and1D hyperopia for age groups under1,1-3,3-5,5-7,7-9and9-10 years respectively.The patients were regularly followed at1,6,12and24 months for changes in axial length and refraction and complications such as glaucoma, amblyopia and lens dislocation.
|
|
Results:
|
Overall 99 eyes from 88 patients with congenital cataract aged5.34±1.02years(range3mo-13years)were studied.Mean follow-up period was1.75±0.84years.
The amount of induced hyperopia after surgery was as expected in all age groups.(All Ps> 0.05)The least error from the desired value was in age under 1 year group7±1.50(P>0.999)and the highest was in7-9years age group2.37 ±1.71(P= 0.06).The highest amount of myopic shift and AL change was in under 1 age group(3.96 ± -1.02D and0.85mm respectively)over two years.

|
Conclusion:
|
Inducing hypermetropia is an effective way to decrease or delay myopic shift after pediatric cataract surgery with primaryIOL implantation.However,intensive amblyope therapy is needed.
