Evaluation of the central vault following implantable phakic contact lens and its correlation to horizontal white to white corneal diameter by anterior segment optical coherence tomography

Background: Implantable Phakic Contact Lenses have been developed as a cost-effective alternative to Visian Collamer lenses for refractive correction. Aim of the work: evaluate central vault implantable phakic contact lens (IPCL) and its correlation horizontal white (WTW) corneal diameter using anterior segment optical coherence tomography. Patients Methods: 30 eyes that match inclusion criteria IPCL V2.0 implantation were studied. Two groups divided study between pre-operative post-operative vault: group 1 with WTW < 12 mm 2 ≥ mm. Results: Visual acuity spherical equivalent improved post-operatively P value 0.01, IOP increased maximally at week month post operatively but declined 6 months 0.01. Central in decreased from 1st till end 0.05. While 2, it > Comparison showed mild difference all visits Also was negative Conclusion: is safe effective approach correction high degrees errors or when surgery contraindicated. Also, no found vault.
