Phacoemulsification Cataract Surgery

Purpose: To compare the post-op visual quality of spheric and aspheric acrylic yellow tinted intraocular lens following phacoemulsification cataract surgery. Place of study: Al-Majeed Laser Eye Hospital. Methods: Total 60 subjects (aged 40-65years) with age related mature cataracts were included. Data was assembled by non-probability convenient sampling technique at Al-Majeed Laser Eye Hospital. All patients presenting with mature cataract were include in this study without any other pathology and fundus abnormality. Pre and post-operative visual acuity was measured by using standard snellen visual acuity testing chart. For the purpose of accuracy repetitive values were taken for each patient. Post-operative vision was recorded one month followed by phacoemulsification. Comparisons was made between spheric and asphereic acrylic yellow tinted intraocular lens by applying (descriptive) statistics and paired sample t test for the analysis of results. Results: Quality of vision was compared post-operatively after implantation of aspheric hydrophilic acrylic IOL and spheric IOL in posterior chamber under the same phaco surgeon. All subjects after intra ocular implantation had better corrected visual acuity of 6/9 and more improved 6/6. There were found statistically differences in recorded visual acuity with aspheric yellow tinted iol implanation and spheric iol (p = 0.15) between the two types of intra-ocular lens. The mean, standard deviation, t-value found with spheric IOL were.1867, .18889, 2.517 respectively. However, of aspheric hydrophilic acrylic intra-ocular lens mean, standard deviation and t values found .800, .13493 and 2.5493 respectively. There was significant variance in statistics and quality of vision between the two types of lenses. Conclusions: This study concludes that post –operative improvement in quality of vision was better with aspheric hydrophilic yellow tinted lenses than spheric iol implantation. Implanting a foldable aspheric acrylic IOL gave much advantage in visual outcome to pseudophakes by protecting retina from light of shorter wavelength and decrease of chromatic aberration under the photopic circumstances particularly in subjects at hazard of age-related macular degeneration (AMD).

Abstract Background This study aimed to assess visual outcomes, quality of vision and patients’ satisfaction of a trifocal diffractive intraocular lens after cataract surgery with phacoemulsification. Results The study included 36 eyes that underwent implantation of trifocal diffractive intraocular lens (IOL). The residual mean postoperative spherical equivalent was − 0.40 ± 0.29 diopters. Mean Uncorrected distance visual acuity was 0.80 ± 0.16 decimal (snellen equivalent 25 ft) while mean Uncorrected intermediate visual acuity was 0.82 ± 0.31 decimal (snellen equivalent 25 ft) and mean Uncorrected near visual acuity (UCNVA) was 0.87 ± 0.20 decimal (snellen equivalent 23 ft). In defocus curve, there was infinitesimal gradual change between the three foci. Contrast sensitivity was just below the inferior limit of normal. Conclusion Trifocal diffractive IOL created a true intermediate focus proved by VA and defocus curve and better quality of vision assessed by contrast sensitivity and high order aberration. Moreover, it was safe and effective for correcting distance and near vision in these patients. Most of the patients were very satisfied and achieved spectacle independence. Trial registration Registration number and date: NCT04465279 on July 10, 2020.

Purpose: To describe a patient complaining of ‘ghosting' and ‘shadowing' after bilateral, sequential cataract extraction with toric intraocular lens (IOL) implantation who was found to have significant eyelid ptosis. Methods: The following is a case report. Results: The patient's complaints arose a few weeks after surgery. By the second postoperative month, the patient's keratometry had changed compared to preoperative measurements. Because of significant ptosis, the patient underwent upper eyelid surgery. Four months later, he was found to have less corneal astigmatism than had been measured prior to cataract surgery. Following 2 stable examinations, a Prevue lens based on Hartmann-Shack wavefront aberrometry was made for each eye, which the patient said significantly improved his quality of vision. Wavefront-guided photorefractive keratectomy (PRK) was performed 6 months after cataract surgery. One year after PRK, the patient's symptoms had disappeared, his uncorrected visual acuity was 20/20 in the right eye and 20/15 in the left, and he was satisfied with his quality of vision. Conclusions: Bilateral toric IOLs were implanted in this patient based on measurements of corneal astigmatism that changed after cataract surgery and changed further after ptosis repair. This case demonstrates the importance of evaluating eyelid position in cataract surgical planning as ptosis can contribute significantly to corneal astigmatism. Patient education is important in the setting of higher expectations from purchase of premium lens implants.
