Altered anterior segment biometrics in cataract patients with retinitis pigmentosa: a propensity-matched analysis suggests patterns of zonular weakness

RP patients exhibit a thicker lens, a more anteriorly positioned lens, shallower anterior chamber depth, and greater corneal astigmatism. These changes can be explained by zonular weakness. Decision-making surrounding intraocular lens selection in eyes with RP, cataract, and zonular compromise may be enhanced through proper identification of preoperative biometric irregularities in the anterior segment.
