The aim of this paper is to assess the optical results and patient satisfaction of small aperture IC-8 IOLs in cataract patients with or without prior ocular procedures. According to the PRISMA statement, a systematic review of full-length original English studies examining the visual results of small aperture IC-8 IOL implantation after cataract surgery in three databases, PubMed, Web of Science, and Scopus was carried out. Significant improvements in uncorrected distance visual acuity have been documented; uncorrected intermediate visual acuity is uncorrected; uncorrected near visual acuity; and patient satisfaction have been reported;.

Abstract Background : The aim was to determine the safety and effectiveness of a trifocal intraocular lens for the correction of presbyopia and patient satisfaction by assessing patient satisfaction. Methods The AT LISA tri 839MP multifocal IOL was used to evaluate presbyopic patients who underwent bilateral refractive lens exchange and implant of the AT LISA tri 839MP multifocal IOL from three centers. For monocular or binocular measurements, there was no statistically significant difference between pre- and postoperative adjusted distance visual acuity. Overall, 84% of eyes had acuity within 0. 2 D and 97. 1% of acuity, with a mean consistency of 87. 5%, 84. 4%, and 78. 1% respectively, and 78. 1% was satisfied with their postoperative, spectacle-free vision. The Nd:YAG laser therapy was used on eight eyes in eight eyes.

Cataract is one of the most common causes of visual impairment due to the opacification of the crystalline lens. Increased intraocular scattering influences cataract patients''s vision by reducing the quality of the retinal images, which is reducing the quality of the retinal pictures. We showed that the AM-SC method can increase contrast sensitivity in the human eyes in vivo with induced scattering.

Abstract Background Severe intraocular hemorrhage is a rare complication of cataract surgery due to the widespread use of minimal-incision cataract surgery. After undergoing cataract surgery, an 86-year-old woman was referred to our center for intraocular lens dislocation. Bleeding significantly reduced in the second surgery compared to the first. The bleeding appears to have originated from the central retinal artery on the optical disc, according to coagulation of the bleeding site with intraocular diathermy, suggesting hemostasis. However, after the second surgery, the patient's visual acuity showed no light acuity. After undergoing cataract surgery, a significant intraocular hemorrhage may have occurred from the central retinal artery. In those cases, general anesthesia with a lower blood pressure could be helpful, considering the possibility of difficult hemostasis in the case of bleeding from the retinal artery.

The cataract surgery in eyes with and without glaucoma results in sustained intraocular pressure reduction, but it is also unknown which glaucoma patients will achieve clinically significant reductions. The purpose of our prospective intervention study was to determine if the relationship between medically controlled patients with pseudoexfoliation glaucoma and nonglaucomatous patients was measurable. The preoperative IOP, AL, and the PD ratio were both predictors of the absolute and percent IOP decrease in the PXG group, as well as the percentage IOP reduction. Both the univariate and multivariate studies found RLP to be a reliable predictor of absolute change in the IOP in multivariate analysis, and the percentage change in both the univariate and multivariate studies. The only important variables in the control group that could predict absolute change in the postoperative IOP were the preoperative IOP and the PD ratio. Both in the PXG and nonglaucomatous eye, the cataract surgery results in an IOP decrease.

Purpose of the Paperwork In cataract surgery, the aim was to determine the physical results of digital and slit-beam manual marking for toric intraocular lenses. Methods All patients with cataracts and normal corneal attigmatism greater than 0. 75 diopters underwent cataract surgery and astigmatism correction between June 2019 and June 2020. In one group, Callisto eye image-guided technology was used to identify the target axis of the toric IOL and the site of the incision, while preoperative manual slit-beam marking was used in the other group. The mean residual refractive cylinder was 0. 42 % in the digital group and 0. 40 in the manual group at 3 months after surgery, and 0. 39 u00b1 0. 40D in the manual group. About 42% of eyes in the digital group and 61% of eyes in the manual group had a rotation within 10-30% of the intended axis, with 42 percent of eyes within 10u00b0 of the intended axis and 61% of eyes in the manual group having a rotation of 0u20132u00b0.

After cataract surgery with phacoemulsification, this research was designed to determine the visual results, quality of vision, and patient satisfaction of a trifocal diffractive intraocular lens. Meaning uncorrected distance visual acuity was 0. 80 decimal, which was 0. 80 percent higher than the mean uncorrected intermediate visual acuity. Conclusion: Trifocal diffractive IOL developed a true intermediate focus, demonstrated by VA and defocus curves, as well as improved quality of vision assessed by contrast sensitivity and high order aberration.

This retrospective review looked at the postoperative results of patients undergoing routine phacoemulsification with toric intraocular lens implantation in FS-AK and patients undergoing standard phacoemulsification with toric intraocular lens implantation. The postoperative bare vision was significantly better and corrected visual acuity in the toric IOL group than in the FS-AK group. Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation are safe and effective methods for astigmatism correction at the time of cataract surgery. With toric IOL implantation, the result has a better visual result than the combined FLACS and FS-AK at 6-month follow-up.

Abstract Aims To compare the effectiveness of astigmatic correction of simultaneous femtosecond laser-assisted intrastromal keratomy keratomy, as a result of femtosecond laser-assisted cataract surgery and toric intraocular lens implantation during cataract surgery in moderate astigmatismus. Designs: Retrospective observational research, Tertiary Care Medical Center Methods We retrospectively reviewed medical records of patients who underwent astigmatic correction by a femtosecond laser-assisted intrastromal AK with FLACS or toric IOL implantation. Both patients had senile cataracts with corneal astigmatism ranging from + 1. 00 to +2. 00 diopters before cataract surgery. According to the toric IOL group, the mean preoperative and 6-month postoperative refractive astigmatism was 1. 85 mm and 0. 01 D, respectively, and 1. 81 and 0. 61 u00b1 0. 51 D. In FLACS, a Femtosecond laser-assisted intrastromal AK may be an effective therapy for reducing astigmatism and toric IOL implantation in cataract surgery.

Abstract Background: Objective: To assess the effect of toric intraocular lens implantation in cataract patients with corneal opacity and high astigmatism. Using a rotating Scheimpflug camera, posterior astigmatism was determined, considering posterior astigmatism. We investigated residual acuity, uncorrected visual acuity, and best corrected visual acuity 2 months after toric intraocular lens implantation. Results: Surgical UCVA and BCVA were statistically better than preoperative UCVA and BCVA. Compared to preoperative refractive astigmatism, postoperative residual refractive astigmatism was statistically reduced. All eyes developed postoperative visual acuity that was equal or higher than the preoperative one. Conclusion: Toric intraocular lens implantation in cataract patients with corneal opacity can result in significant negative correlations with postoperative UCVA and BCVA. Toric intraocular lens implantation should be considered by cataract patients with corneal opacity and high astigmatism.
