Effects of Co-Solvents on Loading and Release Properties of Self- Assembled Di-Peptide Building Blocks, Towards Drug Delivery Applications.

Background: Due to their solid-like porous structure, molecular organogel and microcrystal structures have the capabilities of loading drug molecules, encapsulation, and extended release, all considered as essential properties in drug delivery applications. Phases of these structures, however, depend on the solvent used during the gelation process.

Objective: Understanding the phase transition between organogel and microcrystal structures through adjusting the mixture ratio of different co-solvents.

Comparison of Scheimpflug and swept-source anterior segment optical coherence tomography in normal and keratoconus eyes.

Purpose: The purpose of the study was to assess the agreement of anterior segment optical coherence tomography with its older well-known opponent i.e., Sheimpflug imaging in evaluation of the cornea in normal and keratoconus subjects.

Comparison the post operative refractive errors in same size corneal transplantation through deep lamellar keratoplasty and penetrating keratoplasty methods after sutures removing in keratoconus patients.

Background: Corneal transplantation is a surgery in which cornea is replaced by a donated one and can be completely penetrating keratoplasty (PK) or included a part of cornea deep lamellar keratoplasty (DLK). Although the functional results are limited by some complications, it is considered as one of the most successful surgeries. This study aimed to compare the refractive errors after same size corneal transplantation through DLK and PK methods in keratoconus patients over 20 years.

Comparison of the findings of endothelial specular microscopy before and after corneal cross-linking.

Background: To report the long-term findings of corneal cross-linking (CXL) with riboflavin drops on the corneal endothelial cell.

Materials And Methods: In this prospective non-randomized study, we aim to assess the long-term safety of CXL on the corneal endothelium for the treatment of progressive keratoconus, by endothelial specular microscopy. A total of 68 eyes of 42 keratoconus patients were selected.
