Long-term outcomes following primary intraocular lens implantation in infants younger than 6 months.

ABSTRACT:

Purpose

To study the long-term safety profile and visual outcomes of primary intraocular lens (IOL) implantation in infants <6 months of age.

Methods

This was a retrospective observational study conducted at a tertiary eye care center in South India. Infants under 6 months meeting the selection criteria who underwent cataract surgery (lens aspiration, primary posterior capsulorhexis, and anterior vitrectomy) with primary IOL implantation between January 2008 and December 2011 and minimum 3-year follow-up were included. Patient demographics, serial refractions, visual acuity, complications, and associated amblyopia/strabismus were reviewed. Visual acuity, myopic shift, and complications were the outcome measures.

Results

Sixty-nine eyes of 38 infants (31 bilateral; mean age: 4.6 months) were reviewed. Mean follow-up was 51 months (range: 36-84). Median logMAR best-corrected visual acuity at the final visit was 0.74 (interquartile range [IQR]: 0.50-0.98) in eyes with bilateral cataracts and 0.87 (IQR: 0.60-1.14) in eyes with unilateral cataracts with an average myopic shift of 6.7 diopters over 4.2 years. Most common postoperative complication was visual axis opacification (VAO) (13 eyes, 18%), necessitating membranectomy followed by pigmentary IOL deposits (11 eyes, 15%), and IOL decentration and glaucoma in four eyes each (5.6%). Mixed linear effect model found no significant association of age, gender, laterality, and postoperative complications with final visual acuity (P ? 0.05). Eyes with unilateral cataracts had a greater myopic shift than bilateral cases (P = 0.03).

Conclusion

Primary IOL implantation in infants <6 months is reasonably safe in appropriately selected infants. VAO was the most common postoperative complication, and a large myopic shift was observed.

Project description:The aim of this study was to evaluate the long-term visual outcomes and factors affecting visual results in children undergoing secondary intraocular lens (IOL) implantation following primary congenital cataract extraction.Children with congenital cataracts who underwent secondary IOL implantation for aphakia at the Eye and ENT Hospital of Fudan University between January 1, 2001, and December 31, 2007, were retrospectively reviewed. One eye was randomly selected in children with bilateral cataracts. Laterality, type of cataract (total or partial opacity), sex, age at primary and secondary surgeries, visual axis opacity (VAO), compliance with amblyopia therapy, postoperative ocular complications, refractive error, ocular alignment, and best corrected visual acuity (BCVA) at last follow-up were recorded; potential factors that might have affected the visual results were evaluated.Seventy-six bilateral and 34 unilateral congenital cataract cases were analyzed; the mean ages of the children were 12.70±5.06 and 12.50±2.71 years at final follow-up, the mean follow-up periods from IOL implantation were 94.93±24.22 and 109.09±18.89 months, and the mean BCVA (Log MAR) values were 0.51±0.37 and 1.05±0.46, respectively. Final BCVA after secondary IOL implantation was significantly associated with laterality, type of cataract, age at primary cataract extraction, compliance with amblyopia therapy, and refractive correction after surgery. No significant associations were found between BCVA and sex, age at secondary IOL implantation, VAO, or other ocular complications. The most common ocular complications were VAO and elevated intraocular pressure after surgery. There were no other complications, with the exception of one eye with IOL dislocation.The results indicate that the important determinants of long-term visual outcomes in children with congenital cataracts undergoing secondary IOL implantation are laterality, cataract type, age at initial cataract extraction, compliance with amblyopia therapy, and refractive error.

Project description:PurposeTo evaluate the reproducibility of magnitude of postoperative IOL rotation following implantation of a toric intraocular lens (IOL) with modified haptics, in comparison with a Proof-of-Concept (POC) study of prototype IOLs featuring the same haptic design.Patients and methodsA post-market, prospective, multicenter, single-arm, open-label clinical study was conducted. TECNIS Toric II IOL (Johnson & Johnson Vision, Irvine, CA, USA, Models ZCU150 to 600) were implanted in 125 subjects and evaluated at 1-day and 1-week postoperatively. An objective photographic method was used to determine postoperative IOL rotation. Uncorrected distance visual acuity (UCDVA), postoperative astigmatism, and surgeon satisfaction were also assessed. Rotation data were compared to the POC study in which two prototype non-toric monofocal IOLs, one with the same haptic design as Model ZCU, were studied.ResultsMean absolute rotation was 0.82° ± 1.0° and 0.84° ± 0.92°at 1-day and 1-week visits, respectively. The percentage of eyes with ≤5° of absolute rotation was 98.9% and 99.5% at the 1-day and 1-week visits, respectively. The magnitude of rotation was similar to the POC study prototype IOLs. At 1-week, mean monocular UCDVA was 0.026 ± 0.135 (~20/21) logMAR and mean residual manifest refractive cylinder was 0.30 D ± 0.35 D. The mean signed axis difference (postoperative minus operative) of the TECNIS Toric II IOL was 0.23° ± 1.27° at 1-day and -0.07° ± 1.25° at 1-week, indicating a clockwise drift. At 1-week, surgeons were very satisfied or satisfied with overall clinical outcomes and rotational stability in 98% of implanted eyes.ConclusionThe TECNIS Toric II IOL, with frosted, squared haptics, demonstrated low magnitude of postoperative IOL rotation, excellent uncorrected distance vision, and minimal residual astigmatism. The POC study design was supported, demonstrating that prototype non-toric monofocal IOLs can predict clinical performance of toric IOLs with the same haptic design.
