Rotational Stability of Toric Intraocular Lenses

Aim of Study To study the short-term rotational stability of toric Intraocular lens. To assess the factors that affect rotational stability. To assess the residual astigmatism with toric IOL implantation. Material and MethodsThis institution based prospective non-randomized interventional longitudinal study was donein the OPD setting of a tertiary care hospital in India over 6 months.All cataract patients attending the OPD with a cylinder power in the range of -1D to -4.11D in the corneal plane were included.The exclusion criteria included patients with ocular problems such as previous intra ocular surgery, pseudoexfoliation syndrome, irregular astigmatism, retinal disease impacting the central visual acuity, glaucoma, fixating problems, zonular instability, previous or intraoperative posterior capsule rupture, ectopic pupil, refractive but not corneal astigmatism, extracapsular extraction or surgical techniques causing unpredictable surgically induced astigmatism,
