Aberrometry Changes Following Surgical Management of Isolated Typical Lens Coloboma

A 23-year-old woman presented with a corrected distance visual acuity (CDVA) of 20/30 (−1.0 −6.5 × 120) and 20/20 (−0.75 −1.75 × 180) in the right eye and left eye, respectively. Examination revealed unilateral isolated lens coloboma in the right eye. The Pentacam HR showed astigmatism of 2.7 × 110.4. Ray-tracing aberrometry (iTrace) showed increased internal defocus (1.098 μm) and higher-order aberrations (HOAs) (total 1.543 μm) in the right eye. Clear lens extraction with a capsular tension ring and monofocal intraocular lens implantation was performed. One month later, the CDVA in the right eye was 20/30 (−0.75 +1.75 × 110). Aberrometry showed a reduction in internal defocus from 1.098 to 0.154 μm and of total HOAs from 1.543 to 0.137 μm. The area under the curve of the modulation transfer function improved from 3.308 to 8.913. Aberrometry is a useful tool for patient education, decision making, and quantifying visual outcomes.
