Insights
Infants receiving intraocular lenses (IOLs) during cataract surgery had higher complication rates than those treated with contact lenses. However, the functional impact of these complications did not clearly favor either treatment group after one year.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Clinical Trials
Background:
- Unilateral congenital cataract management requires careful consideration of surgical techniques.
- The Infant Aphakia Treatment Study (IATS) investigates treatment options for aphakia in infants.
- Intraocular lens (IOL) implantation versus contact lens correction is a key area of research.
Purpose of the Study:
- To compare complication rates and severity in infants undergoing cataract surgery.
- Evaluate outcomes with and without intraocular lens (IOL) implantation.
- Assess intraoperative complications, adverse events, and additional surgeries.
Main Methods:
- Prospective, randomized clinical trial involving 114 infants with unilateral congenital cataract.
- Multicenter study comparing primary IOL implantation versus contact lens correction.
- Analysis of intraoperative complications, adverse events, and additional intraocular surgeries during the first postoperative year.
Main Results:
- The IOL group experienced significantly higher rates of intraoperative complications (28% vs. 11%), adverse events (77% vs. 25%), and additional intraocular surgeries (63% vs. 12%).
- Iris prolapse was the most frequent intraoperative complication.
- Visual axis opacification was the most common adverse event and reason for reoperation.
Conclusions:
- While IOL implantation led to numerically higher rates of complications and adverse events, the functional impact was not definitively different between the IOL and contact lens groups at one year.
- Further research may be needed to fully elucidate the long-term functional outcomes.
Purpose:
To compare rates and severity of complications between infants undergoing cataract surgery with and without intraocular lens (IOL) implantation.
Design:
Prospective, randomized clinical trial.
Participants:
The Infant Aphakia Treatment Study (IATS) is a randomized, multicenter (n = 12) clinical trial comparing treatment of aphakia with a primary IOL or contact lens in 114 infants with unilateral congenital cataract.
Intervention:
Infants underwent cataract surgery with or without placement of an IOL.
Main Outcome Measures:
The rate, character, and severity of intraoperative complications (ICs), adverse events (AEs), and additional intraocular surgeries (AISs) during the first postoperative year in the 2 groups were analyzed.
Results:
There were more patients with ICs (28% vs. 11%; P = 0.031), AEs (77% vs. 25%; P<0.0001), and AISs (63% vs. 12%; P<0.0001) in the IOL group than the contact lens group. Iris prolapse was the most common IC. The most common AE was visual axis opacification, and the most common additional intraocular reoperation was a clearing of visual axis opacification.
Conclusions:
The rates of ICs, AEs, and AISs 1 year after surgery were numerically higher in the IOL group, but their functional impact does not clearly favor either treatment group.
