Visual Outcome of Cataract Surgery

Abstract

Purpose: To assess th e visu al ou tcom e of cataract su rgery in a tertiary h osp ital in N igeria. Methods: Th ree h u n d red an d seven ty eyes (370) that had cataract su rgery in th e op h thalm ology d ep artm ent of Un iversity of Ben in Teach in g H osp ital (UBTH) from Ju ly 2007 to Decem ber 2008 w ere in clu d ed in the stu d y. Case record s w ere retrieved an d d ata from them analysed. Th e age ran ge w as 4 to 95 years (m ean age 41.1 years). Th ere w ere 181 m ales an d 189 fem ales. Sen ile cataract w as the com m on est (64.6%) typ e, follow ed by trau m atic cataract (13%). Extracap su lar cataract extraction w ith p osterior cham ber intraocu lar len s (IOL) im p lan t (75.4%) w as th e com m onest p roced u re, follow ed by ECCE w ith an terior cham ber in traocu lar len s im p lan t (11.6%), ECCE w ithou t IOL (4.1%) and in tracap su lar cataract extraction w ith or w ithou t IOL (8.9%). Results: Preop erative visu al acu ity w as less th an 3/ 60 in 73.8% an d 6/ 18-6/ 60 in 4% of th e eyes. The best corrected p ostop erative visu al acu ity at 6 w eeks w as 6/ 6-6/ 18 (good ou tcom e) in 161 (43.5%) eyes, bord erlin e in 107(28.9%) an d p oor in 73 (19.7%). The best corrected visu al ou tcom e at 6 m on th s w as good in 221 (59.7%), bord erlin e in 59 (15.9%) an d p oor in 34 (9.3%) eyes. Th e visu al ou tcom e w as u n kn ow n in 56 (15.1%) eyes. Conclusion: Th e visu al ou tcom e after cataract extraction in th is cen tre is still less th an th e WH O recom m end ation of 90% for best corrected visu al acu ity of 6/ 6-6/ 18 vision. Th ere is th e n eed for biom etry, good p atient selection, p rop er m an agem en t of com p lications and sp ectacle correction of refractive errors in ord er to im p rove visu al ou tcom e after cataract extraction.

Cataract surgery outcomes: comparison of the extracapsular cataract extraction and manual small incision cataract surgery techniques

“…Furthermore the sample consisted of a similar proportion of male and female participants are most reported in the literature. 4 , 29 , 34 …”

“…A six-week follow up period in this study was considered adequate to allow for resolution and correction of any refractive error induced during the surgery. 34 Some studies have used slightly longer post-surgery follow up periods of six to eight-weeks and they tend to show better post-surgery VA outcome. 25 , 34 , 36 , 38 One-hundred participants presented with poor pre-surgery VA which is in agreement with the literature where the majority of study participants pre-surgery VA was poor.…”

Risk factors that associated with visual outcome of community based cataract surgery

“…The reason the occurrence of visual improvement at repair at 6 weeks postoperatively is the recovery of intraocular inflammation after surgery and correction of remaining refractive disorders. 18 Other reasons for the lack of operating results are poor selection of patients, previous comorbidities, intraoperative complications, and uncorrected refractive disorders. The presence of other pathologists such as glaucoma, cataract complications due to uveitis, and agerelated macular degeneration can be considered important risk factors for poor postoperative cataract outcome.…”

“…In a comparative study of various complications of cataract surgery, posterior capsule rupture occurred in 1.5-3.1%, vitreous prolapse in 0.8-1.39%, the nucleus dropped at 0.18-1%, and supracoroid bleeding at 0.07-0.14% cases. 18 Castells et al reported patients who underwent phacoemulsification had intraoperative complications compared to ECCE, especially for intraoperative iris. 19 The cataract surgery survey in Iran from 2000 to 2005 also reported the lowest risk of intraoperative complications in phacoemulsification (2.29%) and highest in ICCE (36.17%).…”

Impact of cataract surgery on vision-related quality of life

“…11,37,39 A 6-week follow-up period is considered as adequate to allow visual recovery and rehabilitation to stabilise. 37,39,40 Vision-related quality of life questionnaires aim to measure the impact of vision loss on an individual's daily life. 36 Many questionnaires have been developed to evaluate pre-surgery and post-surgery VRQoL in individuals with cataract.…”
